Here is the alias and listen statements.
listen=10.200.0.228:5060 # INSERT YOUR IP ADDRESS HERE
listen=10.200.0.228:6060 # INSERT YOUR IP ADDRESS HERE
listen=210.14.7.5:5060 # INSERT YOUR IP ADDRESS HERE
listen=210.14.7.5:6060 # INSERT YOUR IP ADDRESS HERE
port=5060
children=16
dns=no
rev_dns=no
alias=o6.ol.com
alias=10.200.0.228
alias=210.14.7.5
In the server, there are 2 interfaces (internal and external). I put
both of them in the alias and listen statement. Anything wrong here?
Why openSER fail to recognize the request (CANCEL) as targeted to
itself?
How do you solve and prevent this problem? As the performance of the
server will degrade when this loop happen. It must be a way to
prevent it otherwise users connected to the system will be affected.
reduce the time-out parameter?
reduce the number of hops?
Thanks for help!

Sometimes I found similar behaviour and a 483 Too Many Hops at the end
when openSER does not recognize the request (CANCEL) as targeted to
itself. The problem is that 10.200.0.228 does not validates against
the myself statement and the server sends the request to the IP
present in the Req-URI, which happens to be the openSER IP address.
This proceeding is repeated until the Too Many Hops is reached.
There was another issue with CANCEL to INVITE transactions which have
not finished (no reply>199 received) because the CANCEL does not match
the transaction when the caller "hangs up" before the callee "picks up
the phone". I think this is more a openSER internal issue which might
have been solved...apologies if this issue has been closed.
Hope it helps,
Samuel.
2006/5/4, unplug <maillisting(a)gmail.com>om>:
I have experienced a problem (looping problem?)
in the system. From
the log (ngrep) below, the cancel message issues a loop and it will
affect the performance of the system. User can't dial/receive call
after the loop happened.
How and why this loop will created? Does it related to the rtpproxy
that I am using in the system? Any one can give me some hints?
Thanks,
unplug
Note: 10.200.0.228 is an openser server.
