Isolate the possible “root cause” based on the symptoms observed. First find the symptom listed (in left-most column) in the guide, then: i. For each symptom, there is a possible cause listed in the next column ii. Try each possible resolution (column to the right) for that cause iii. If the resolution does not clear the trouble or eliminate the symptom, then go to the next possible cause associated with that symptom (usually the next row) iv. Several different root causes may be associate with the same symptom 3. Be systematic, make only one change at a time and observe the results. a. Does the symptom persist? If so, proceed to the next possible cause. b. If the symptom disappears, check for cause and effect (reintroduce the change to see of symptoms re-appear). 4. Eliminate obvious and easy to verify causes first, like physical connections, (layer 1 and 2) before proceeding to more complex causes (layers 3 and higher). 5. Document all of the different troubleshooting steps taken. a. Precise and detailed information will help you when you escalate the problem. b. For example, you may want to print out this sheet and check-off each procedure that has been used. 6. Finally, you can compare “normal” settings of the equipment with the current parameter settings of the problematic equipment. If you find a difference between the “normal” settings and the problematic equipment, try changing the settings of the problematic equipment to match the settings of the “normal” equipment.

Symptom Root Cause Resolution

Red LED on LED board is on. Major Alarm is present. The command show faults indicates that the fault in the Root Cause column is present.

Possible fault with the Media Gateway Processor (MGP) or Media Modules. Synchronization signal lost.

1. Check that provisioned clock-sync source has a good signal by issuing a Media Gateway Processor (MGP) Command Line Interface (CLI) command show sync timingProcedure for setting synchronization timing sources on E1/T1 MM or MM710:2. Be sure that the E1/T1 MM has been added properly on the Avaya™ S8300 Media Server or Avaya™ S8700 Media Server, otherwise go to System Access Terminal (SAT) and issue a ADD DS1 command before going to the MGP CLI and issuing a set sync interface or set sync source command. Otherwise the MGP CLI will not allow these commands to be executed.3. Go to the MGP’s CLI, and first specify the primary and secondary clock sources for synchronizing the E1/T1 span, using the set sync interface command. Note: You don't specify the internal clock source from the CLI - only the primary and secondary. The local clock is "built-in" and not provisionable.4. Issue a set sync source command to set to the specific MM710 E1/T1 Media Module to be used as the active clock reference.5. Verify whether or not these commands were executed by issuing a show sync timing command to ensure that the source is provisioned and active, or visually inspect the Yellow LED on the MM710 Media Module.

Note: When the Yellow LED is on 2.7 seconds and off 0.3 seconds, this means the tone-clocksynchronizer is in “active” mode, and an external synchronization source is being used as a synchronization reference. Setting the sync timing was successful.

When the Yellow LED is on 0.3 seconds and off 2.7 seconds, this means the tone-clocksynchronizer is in “active” mode and the internal (on-board) clock is being used as a synchronization reference. Setting the sync timing was not successful.

For more details, please consult the maintenance documentation under LEDs and E1/T1 Media Module; go tohttp://www.avaya.com/support and select Product Documentation.

Voice Quality G700 Troubleshooting Page 1

Symptom Root Cause Resolution

a) IP Phone does not get Dial-tone b) No talk path between IP Phone and a DCP/Analog phone c) No talk path between IP Phone and a Trunkd) One-way talk path.

No VoIP resource available.

1. Check if there is an Avaya™ G700 Media Gateway or a prowler resource available with the right codec for the IP Phone,

using the SAT commands described in the Avaya MultivantageTM Administrators guide. 2. Issue a SAT command display events and look for a denial event (2049) for no available VoIP resource.3. If there is no resource, then administer one. 4. If there is a resource, then check for connectivity between the source and the destination using the ping command. 5. If the problem persists, then escalate.

a) IP Phone does not get Dial-tone b) No talk path between IP Phone and a DCP/Analog phone c) No talk path between IP Phone and a Trunkd) One-way talk path.

VoIP on Avaya™ G700 Media Gateway is insane.

1. Issue a SAT command display events and look for a denial event (2049) for no available VoIP resource. 2. Using telnet, go to the Media Gateway Processor (MGP) CLI. Use the command show voip vX where X is the slot number of the VoIP ( 0- for VoIP on the motherboard, 1-4 for MM760 VoIP Media Modules). Check if the Admin State is "Release". 3. Verify that the static IP address is non-zero, that the current IP address matches the static, that there is a valid MAC address, and that the resources in use are fewer than the allowed maximum number. 4. Also check if there are any faults. Refer to the Maintenace manual to clear the faults. If the Admin State is OK and if there are no faults, use the command ping mgp xxx.xxx.xxx.xxx, where xxx.xxx.xxx.xxx is the IP address of the VoIP in question. If you cannot ping the VoIP, then the VoIP is insane. 5. Go to the 'configure' mode. Use the command reset voip vX, where X is the slot number of the VoIP. Wait for a couple of minutes, then use the command show voip vX. Verify that the VoIP is in normal state. 6. Now check if IP Phones get dialtone. If not, escalate the problem.

Echoes during an IP call - particularly between IP phones and shuffled calls.

Data network delay.

1. If an IP Softphone is involved, check the latency on the data network or LAN by selecting audio monitor for ping delay. 2. If it is greater than 150 ms, echo may be due to delay. If delay is significant (Avaya™ VoIP Monitoring Manager or a 'sniffer'-like internet advisor), echo can be amplified by delays. Reduce latency in the data network. 3. Try using VLAN tagging and QoS settings.

1. Check to see if echo cancellation is turned on in the SAT connected to the S8300: Example: display ds1 1v42. If Echo Cancellation is not turned "ON", issue a change ds1 [port] command: Example: change ds1 1v43. Change fields to the following settings: Echo Cancellation: [y] EC Direction: [inward/outward - for the GA release it is actually opposite of what it’s suppose to be on the MM710 (for firmware version 2 and earlier)] EC Configuration: [1]4. Issue a change trunk-group [trunk group #] command associated with the ds1: Example: change trunk-group 185. On page 2 set Ds1 Echo Cancellation? to ’y’.6. If Echo Cancellation is not displayed, escalate the problem and contact Avaya or your Authorized Avaya Business Partner to turn ON Echo Cancellation (must purchase).Level 2: If Echo Cancellation is not turned "ON" for a DS1, and the customer reports that the SAT screen doesn’t display an option to turn Echo Cancellation ’ON’, login to the SAT to check the system-parameters customer-options form:1. Issue a display system-parameters customer-options command.2. On page 1, check that "Maximum Number of DS1 Boards with Echo Cancellation [1]" is set to greater than "0", or to thenumber of DS1 boards under control of the S8300.3. On page 2, check that the echo cancellation feature is set to ’enabled’ or ’y’.4. Issue a change ds1 [port] command: Example: change ds1 1v45. Change fields to the following settings: Echo Cancellation: [y] EC Direction: [inward/outward - for the GA release it is actually opposite of what it’s supposed to be on the MM710 (for firmware version 2 and earlier)] EC Configuration: [1]6.

IP phone is in ’discovery’ state and never comes out of it.

May have wrong controller IP address, or the server is down, or one or more of the network nodes are down or not connected properly.

1. Check the server IP address by pressing "MUTE or HOLD" button + ADDR + # and use # to navigate, until you see the "CallSv" the IP address. This should be a valid CallServer IP address (S8300/S8700). If you do not know your "CallSv" IP address, contact your system administrator. 2. Also make sure the Router address and Mask values on the IP station are properly set. You can see ROUTER and MASK values by pressing the # key. Refer to the troubleshooting section of the IP phone 4600 series documentation for additional troubleshooting information. 3. Ping the server from a PC local to the network to make sure the server is up. 4. If the server is up, ping the phone from the PC.5. If the ping command succeeds, escalate the problem.6. If it does not, there is a network problem. Check for network connectivity.

IP-phone display shows "Wrong Set Type".

The set type associated with the extension does not match the IP-set type.

1. Re-enter your extension after pressing #, if you know the extension, and follow the steps. 2. Otherwise, contact your system administrator to find out your extension and password for the IP-set. 3. Refer to the troubleshooting section of the IP phone 4600 series documentation for additional troubleshooting information.

IP-phone display shows "No Ethernet".

No cable or bad cable or cable in the wrong port.

1. Check that the other end of the cable is connected to a switch or hub.2. Make sure the cable is CAT5 and plugged in to the port indicated by the phone symbol and is not a cross-over cable. 3. Refer to the troubleshooting section of the IP phone 4600 series documentation for additional troubleshooting information. 4. If the problem persists, escalate.

IP station screen indicates extension or password mismatch.

The extension or the password is not administered on the server.

1. If you know you extension and password, please enter them. 2. If you still see an error, either your extension is not present on the server, pointed by CallSv on your phone, or the password does not match. 3. Check if you have the right server IP address by pressing "MUTE or HOLD" button + ADDR + # and use # to navigate, until you see the "CallSv" the IP address. This should be a valid Call Server IP address. 4. If you do not know your "CallSv" IP address, contact your system administrator. 5. Refer to the troubleshooting section of the IP phone 4600 series documentation for additional troubleshooting information.

No Dial tone on IP Phones.

IP station may not be registered or has no VoIP resources in its network region.

1. Make sure the IP station is registered. If registered, you would see a red-LED on the first call appearance button, and, if you have a display phone, you may see the date or a green LED light up on thefirst call appearence when you go off hook.2. If the IP station is registered, login into the system SAT terminal, and make sure an Avaya™ G700 Media Gateway or a prowler board is in your network region. To find this out, do 'display ip-network-map' on the SAT, and verify that the IP address of your station falls in the range defined by the IP address in the first two fields. 3. If it does, look at the last column for this entry. If you find your IP station IP address in the scope, that is the network region of your IP phone. If you do not find one, go to the next step. 4. Issue a display ip-interfaces command on the SAT. This returns a list of names with an associated network region in the last column. If you do not know your network region look for the IP stations "CallSv" IP address, and look for the associated network region number.5. Now you should have a network region number. In the same form, look for the media procesor boardIP address in the same network region. If you find one you have VoIP resources. 6. Otherwise, cancel out of the form and issue a list media command on the SAT. This returns a list of G700s with associated network region. 8. Issue a display media x command, where x is the G700 number, for each of the G700s to display its network region number. 9. If you find a G700 with the same network region number as your station region number, you have VoIP resources. 10. If not, there are no VoIP resources. In such a case, make sure the station network region is served by at least one network region.11. Refer to the troubleshooting section of the IP phone 4600 series documentation for additional troubleshooting information.

IP phone looks dead. May not have any power.

1. If the phone has no local power supply, and it is not a 4630 phone, make sure it is getting power from the Ethernet cable. 2. Make sure that the far end of the cat5 Ethernet cable is plugged into a P330-PWR. 3. If it is a 4630 phone, provide a 4630 local power supply.4. A regular IP phone can be powered locally, using a midspan power unit or the P330-PWR.5. Once power is available, recycle the power, either by removing the local power supply or removing the Ethernet cable in case of in-line power supply. 6. If this does not fix the problem, replace the phone.

IP Phone keeps rebooting.

Bad phone, or wrong cable type, or intermittent power problems.

1. Swap the phone with another to see if the rebooting problem follows the phone.2. If it does, replace the phone.3. If not, check the cable. It must be a CAT5 type.4. If the cable is correct, begin checking power sources, connectors, and jacks for problems.

IP phone displays the message "discovering" and cannot login to the controller.

No network connectivity between the IP phone and the controller.

1. Verify that the subnet can see the DHCP server. 2. Verify that the DHCP scope is correctly sending out information to the scope. 3. Check to see if the IP address on the phone is in the correct range of valid IP addresses. If not, then set the IP address to a correct address. 4. Check the IP address of the S8300/S8700. 5. Check the IP address of the router. 6. If all of this is correct, then use a PC on the LAN to ping the S8300/S8700 by issuing a ping command from the PC. 7. If the ping is successful , then check from the S8300/S8700 webpages if you can ping the IP phone in question. 8. If the pings do not succeed, try swapping out the cable, and the IP phones, as well. Otherwise, escalate the problem.

Physical layer problem - wrong cable.

1. Verify that the internal P330 Processor port does not report an error.2. Make sure that you have the correct cable (CAT 3 cable can be used for 10Mb connections, but CAT 5 should be used for 10/100 connections). 3. Check the cable connections, and, if necessary, replace the cable.

Intermittent problems (unexplained IP talk path problems; G700 Media Gateway reboots).

Switch port configuration - incorrect negotiation of speed and mode.

1. Verify that the ports that have 'autonegotiation' enabled have not downgraded the speed, or that there is not 'half/full duplex' mode mismatch that usually generates late collisions. Use the P330 commands: show port [module#/port#], where module# is the stack number; EXT1= port1; EXT2=port2. show rmon stat <port>2. If there is a mismatch, change the speed or mode appropriately, using the commands: set port speed <module#/port#> [10MB|100MB] set port duplex <module#/port#> [full|half].

Intermittent problems (unexplained IP talk path problems; G700 Media Gateway reboots).

IP address duplication.

1. Disconnect from the network or shutdown the device with problems.2. Try to ping the IP address from the internal P330 Processor or the Media Gateway Processor (MGP). 3. If the ping succeeds, there is a duplicate IP address. 4. Try to telnet to the IP address, or look in the ARP tables to detect the conflicting device.

G700 recovery is not set properly.

The G700 recovery is shown by the Media Gateway Processor (MGP) CLI command "show mgp recovery". Here is an example of valid values : “Primary Search = 1”, “Total Search = 30”, “Transition Point = 1”. The Primary Search is the time in minutes during which the G700 is going to try to connect to the S8300/S8700. If the primary search time is too small, the G700 may not have enough time to register. If it's too big and the S8300/S8700 is not reachable, the G700 may not register with a secondary controller (possibly an Avaya™ S8300 Media Server configured as an LSP). The Total Search is the total time of the cycle during which the G700 is going to try to register with different S8300s/S8700s. If it's too small, the G700 may not have enough time to register, if it's too big, the G700 may take a long time to find an S8300/S8700 with which it can register. The Transition Point is the point beyond which the S8300/S8700 isconsidered to be a secondary controller.On the MGP CLI, depending on which parameter you need to change, type one of the following commands: set mgp reset-times primary-search <PRIMARY_SEARCH_TIME_IN_MINUTES>, or set mgp reset+F6-times total-search <TOTAL_SEARCH_TIME_IN_MINUTES>, or set mgp reset-times transition-point <TRANSITION_POINT>.
