[Users] Receiving different VIA in INVITE and CANCEL

Tue Feb 7 13:35:02 CET 2006

Hi Bogdan,

Thank you for your reply. 

I used
modparam("tm", "via1_matching", 0)
modparam("tm", "ruri_matching", 0)
and I got the following trace. You can see that the ACK to the Proxy
Authentication Required and the CANCEL have different Via than the
INVITE. I know that this breaks the specs but I thought that these two
modparams should take care of these broken UAs.

Also, any ideas what makes the UA switch ports? Is it a NAT issue? Only
a very small percentage of the same UA behave this way.

thank you for any help

George
