Hi, I am implementing a sip proxy with kamailio and multiple asterisk servers, when kamailio send the OPTIONS asterisk don´t reply, and i see with sngrep tool that in the asterisk servers the SIP message OPTIONS arrives, but has no reply from asterisk, and enabling the sip debug nothing occurs, but the OPTIONS message between asterisk servers is all ok.
On kamailio logs get:
dispatcher [dispatch.c:3159]: ds_options_callback(): OPTIONS-Request was finished with code 408 (to sip:172.20.20.3, group 1)
The SIP traffic arrives the asterisk servers, but asterisk don´t reply the message, (I know this because i can see it with the sngrep tool, because the sip debug on asterisk doesn’t show it) . However when the message is from another asterisk all is ok.
Sip kamailio OPTIONS message from kamailio on asterisk:
OPTIONS sip:172.20.20.3 SIP/2.0
Via: SIP/2.0/UDP 172.16.10.195;branch=z9hG4bKef0b.b1358
CSeq: 10 OPTIONS
User-Agent: kamailio (5.3.4 (x86_64/linux))
