[asterisk-users] issue with sip 180 responses

[Nir Levi]

Hello,

SIP invites are accepted from imitator , but 'SIP 180'  is not
responded back  to imitator. 

 

By inspecting the issue , we can *see* the response is generated and
sent from asterisk (via asterisk logger ("sip debug" )) , but while
sniffing the interface with tcpdump, we can't see 180 response on the
interface.

 

We don't have errors on the interface, firewall is disabled , seems
there's no packet lost  (checked with ping with low interval ) , and
routes are ok ... 

 

By our tests we can see there is a direct connection between the mass of
the calls, and between the lost of sip 180 responses.

 

We're using Asterisk 1.4.4, with real-time configuration, also we made
few *modifications* in asterisk source code (changed app_dial.c,
/app_macro.c, /func_cdr.c)...

 

We're not sure if the problem on the OS Level (Centos 5.2) or in the
asterisk application.

Please assist...

~Nir
