Summary:                    Asterisk Fails SIP Performance Test with  Navtel
Interwatch 9500 Hardware Call Generator
Description: 
- We are facing a lot of issues when we try to test Asterisk on HW call
generator Navtel Interwatch. Navtel Interwatch is an enterprise grade call
generator, Telco usually use it test softswitch and ip pbx equipment.

1) During the dialing, Asterisk sends Notify message on Ring, Interwatch
cannot understand by throwing error.

2) Call test fails with 5060 port, other ports works fine. We have tried
different IP PBX, only Asterisk fails the test with 5060 port. The problem
is that Asterisk send local ip address of caller instead of ip pbx domain.
Need to patch chan_sip.c to fix it.

3) Local Extensions Test: 3CPS, 100 peers, 27 concurrent calls 72 hours
   Result: 45% Skipped calls 60% Successful calls

4) SIP Trunk: Two Asterisk Boxes with each 100 peers and 1 SIP Trunks
  Interwatch --> Asterisk PBX ----> SW ---> Asterisk Box---> Interwatch
