The IX78 for SMB Deployments
both for Hosted SIP Services and SIP Trunking
Intertex Data AB, March 2012

What’s in the IX78?
ADSL2+ modem with Annex A/B/M (24 Mbps DS, 3 Mbps US), or Ethernet WAN (VLAN capable) Triple play and various routing configuration possibilities Router with any port, any service capability and 4-5 port Ethernet Switch Wireless 802.11b/g as Access Point (3 SSID for separate WLANs) Business Firewall Advanced QoS for voice, IP-TV etc. VPN (IPsec with certificate handling) TR-069 and proprietary flexible provision system
Let’s have closer look what can be achieved!
there are outstanding features enabling new applications and services Unique support for standard SIP phones and soft clients on the LAN and WLAN SIP Trunking of PBXs – unequalled interoperability list SIP Proxy, Registrar and PBX-like functionality
and more…
and in addition to VoIP things like 2 FXS ports for analog telephones and FAX with T.38 support FXO port: Real SIP/PSTN gateway + Fallback on WAN loss

SIP is the Most Important Protocol, but…

A common Network and common Protocols changed our lives:
SMTP gave us global email! HTTP gave us the WEB!

SIP is the Internet standard for Live IP Communication: The next step of Internet usage!
Find each other and do something in real time. Telephony being just one application.

However, SIP does not traverse the common NATs and firewalls* separating the LANs from the Internet .
* Live IP Communication Requires: - Locate the person - Set up a session - Open real time media streams

We Need a Future of Live All IP Connectivity!
In the world of Unified Communication and global IP-communication, SIP must be used as general as SMTP for email and HTTP for the Web!

The Intertex & Ingate SIP Architecture
To get general NAT/Firewall SIP traversal:
SIPProxy
SIP Proxy Server, capable of routing to/from various address spaces (NAT)
The routing SIP Proxy Server controls the media through the NAT & Firewall
UserLocation
SIP Registrar for user location information
Firewall & NAT Router
Dynamic NAT & Firewall EngineUsed for NAT/Firewall traversal and also as: - Outbound proxy- Inbound proxy - SIP Server - PBX (The SIP Switch)
Most of these elements used when SIP Trunking
B2BUA invoked in addition when required

The Many Faces of the IX78
In addition to being a router, a firewall, a wireless access point, an ADSL modem etc., the IX78 has several SIP and Telephony related functions:
SIP ATA device (2 FXS ports, 1 FXO port)
SIP E-SBC Gateway for hosted services – LAN and WLAN SIP devices have global SIP connectivity
SIP Trunking E-SBC – Connecting IP PBXs directly to operator’s SIP Telephony Services
Unique SIP support including proxy and registrar, various VoIP network architectures supported, advanced SIP and Telephony routing, built in PBX
All these functions can be used together and at the same time!

Ordinary Voice IADs – Good for Telephony Replication…
InternetInternet
The 5060 SIP-port is just grabbed on the outside to the FXS ports!
Lower level SIP ALGs often cause problems and do not handle more than basic scenarios.
• SIP to the LAN or WiFi• Calls between SIP clients on LAN • Calls between internal ATA ports and LAN clients• Call transfers, 3-party calls, etc.• Using SIP generally over the Internet (Operator “took all the SIP”) (Users must not be deprived of general SIP-functionality!)
Often problems with, or total lack of:
Telephone ports (FXS) on the CPE is a popular way to deploy IP telephony. By logically placing the SIP clients on the outside of the NAT/Firewall, unreliable work-around methods like STUN, TURN and ICE become unnecessary. However, this only gives POTS replication, often even stopping general SIP based services!

No battery draining of WiFi mobile phones, otherwise caused by keep-alive packets* inhibiting sleep mode.* Work-around methods for SIP NAT-traversal like STUN, TURN, ICE and Far End NAT Traversal use frequent keep-alive packets to keep holes in the NAT/Firewall open.

Intertex’ IADs are SIP Capable NAT/Router/Firewalls
InternetInternet
Problems solved where they occur
Wired or wireless SIP clients (phones, soft clients, PDAs)
No special requirements on the SIP Client – Just standard SIP

All Intertex CPEs have a SIP Proxy based SIP aware Firewall/NAT
General, can handle complex call scenarios and all SIP services
Additional functionality available (SIP server, PBX functionality etc.)

IX78 for SIP Trunking
SIP-Trunking for the IX78 Connecting IP PBXs to Operators’ SIP Services
The era of replacing T1/E1/PRI lines for IP connections to operators’ SIP telephony services has begun.
Most IP PBXs require SIP traversal of the enterprise firewall and some special additions.
Intertex’ sister company Ingate has taken the SIP-Trunking lead. http://www.ingate.com/SIP_Trunk_UC_Summit_LA_2010.php
IX78 can enable E-SBC (Enterprise Session Border Controller) functions for SIP Trunking
IX78 includes the same SIP Trunking functionality as the Ingate Enterprise line of E-SBCs!

The IP-PBX Trunk Must Meet Service Provider Trunk
Data LAN only
PBX with PBX with system system phonesphones
PBX Type 1.5
VoIP & Data LAN
PBX Type 2
IPIP-- PBXPBX
Few PBXs are of this type. Asterisk with firewall (IPtables /NETfilter) can be compiled and configured this way, but requires a lot.
Why may an IX78 be required to connect a PBX?1) NAT/Firewall Traversal – Must NAT to same address space!
2) Basic SIP and Network Interoperability - E.g. Authentication, Registrations, UDP/TLS/TCP, Dynamic IP address, etc.
3) SIP Repair - E.g. Call Transfer, Fragmented packets, Bugs, etc. 4) Features - E.g. Remote Users, Administration (remote and local)
5) Security - E.g. Will LAN be opened? Is the PBX designed to be public?

SIP Trunking in Proxy Mode or B2BUA Mode
Proxy Mode IP-PBX talks to Service
Registration/Authentication model must match
Little configuration in the IX78
Service credentials in the PBX
B2BUA Mode (Proxy still doing the basics) IP-PBX only talks to the IX78
Wider separation between PBX and Service
Service Credentials only in the IX78
More SIP Normalization possibilities (e.g. REFER)
Any new operator service platform only requires IX78 reconfiguration (the PBX configuration can remain)

IX78 Architecture and Functionality
All services on different WAN-pipes made available to all terminals on a single LAN / WLAN• All QoS advantages preserved from the conventional port the based architecture• Network clouds may be NATed or in the public address space• Firewall protection on all WAN pipes (PVCs, VLANs etc.)• QoS based routing, in addition to traditional address based routing
Special IP TV requirements • IGMP proxy for multicast IP-TV, with fast leave and multi- to unicast conversion• RTSP proxy for VoD (Video on Demand)• Horsepower and intelligent packet dropping to maintain priority on critical video streams
Full SIP Based Live IP Communication Support • Much more than POTS replication via FXS ports• Full support for SIP on LAN and globally, without unreliable work-around methods• QoS applied to all SIP signaling and media – No client setup required• SIP clients can use either Quality Assured operator service or the Internet. SIP communication can be separated and routed
universally, with best QoS on each network• Support for all SIP services (not just telephony)• Equal treatment and full connectivity between telephony ports (FXS), LAN or WLAN connected clients as well as outside clients• SIP and IMS supported over the VoIP and IMS pipe as well as over the Internet and routed globally
A user attractive architecture for multimedia services and terminals.Plug-in compatible CPE, without changed network architecture!

Initial automated configuration to get up and running
Powerful Provisioning Systems
THEREAFTER:
Continued Configuring – New or updated settings easily distributed
Firmware Upgrade – The CPE can look for new firmware releases and upgrade itself
SIP Switch
Cable, etc. Customer Purchases – Software options, licenses and
even hardware accessories, can be ordered and delivered from IG Shop. Provisioner sells to his customer as usual. Unlocking
of subsidized CPE can also be sold this way.
Use standardized TR-069 and TR-104 or Intertex’ provisioning - easy to integrate with existing customer handling system
