Hi Atle!
Ya, sometimes I found that there is something unusual happened as the UA1
will send the INVITE directly + UA2 public IP to UA2 without going through
SER. Is this what you are mentioning on the ALG issue?
Thanks!
Cheers,
Roa Yu

HI Roa Yo,
Look at the signalling, If you for instance see the callID with
a private IP, and everything else with public IP from the UA.. Then you
are fairly sure there is something happening on the way (ALG).
If you know a user is behind nat, you know he should have private IP's
in his signalling but still has public IP's.
Also if you know your sip-device always uses port 5060, and suddenly you
see traffic from one sip-device that sends from port 15321 and with a
public IP.. you know something is happening on the way.
Just remember,, it CAN look like a alg if ser has been in the picture
since ser can do alot of funnie things with the signalling if you ask it
to ;-)

Hi Michal,
How to check whether the SIP ALG is enabled from the trace?
Thanks.
Cheers,
Roa Yu :)

Looks you have SIP ALG enabled on your NAT, which breaks the call
transfer (no surprise, I haven't seen working SIP ALG yet).
Check OPTIONS request sent by SJphone and received by SER, check NOTIFY
sent by SJphone and received by SER.
Disable the SIP ALG and try again. If you can't disable it, change the
NAT box itself.
