Sipd stores the contact information in the database table:[email protected] => [email protected]

There can be multiple contacts. All registered phones ring, and the first to pick up is connected.

(2) The gateway forwards all PSTN calls to sipd; sip:[email protected]

(3) Sipd looks into the dialplan, finds a mapping 7132=>[email protected] and forwards the call to the current location of “wenyu”.
