[asterisk-dev] "OPTIONS" message support in Asterisk

[Atif Rasheed]

Hi all,

I am trying to OPTIONS message to check entity status. But when my 
SoftSwitch sends OPTION message to Asterisk, Asterisk reponds (sends 
200-ok) on udp src port. where as Asterisk should reply on contact 
information mentioned in "contact" or "via" header.

my SoftSwitch is using different port as a source port instead of 5060, 
but listening on 5060 for SIP. how can I change this behaviour.

example trace attached below

Thank you
Atif
