[asterisk-users] chan_sip.c:10173 handle_response: Dont knowhowtohandle a 202 Accepted respons

Yuan,

It looks like you are getting 202 for SIP Request method MESSAGE.  The 202
response is processed properly.  Need to see the message fully.  You can
capture sip debug if you don't have ethereal.  This will provide more detail
call flow.

Neel,

Thanks for the reply.  I don't have ethereal on the machine and not sure how

to capture - non-graphic terminal environment.  Below is output from 
tcpdump.  In this session, I see two "202 Accepted" from 1.4.0, only one 
"don't know" notice.  Interestingly, identical tests between two 1.2.13 
Asterisk does not produce this.

I assume that this is nothing serious, because the session completes without

any problem, and the message is only a notice.  If anything, I'll simply 
revert to 1.2. (These are non-production.)
