[Serusers] sl_reply replies to source port, not contact port

[Mahatma Sarasvati]

Hello,

I'm using SER from cvs checked out today:
cvs co -r rel_2_0_0 sip_routerMy Cisco 7940G phone is trying to register and is failing. I think because SER is replying to a the port (50650) that the REGISTER request came from, but the phone is not listening on port 50650. The phone never adds Digest Auth stuff into the REGISTER message, so I think its not getting the 401 Unauthorized message.

The REGISTER message is explicit that the Contact should be at port 5060. 

I have a production installation of SER 0.8.14 that is replying to port 5060 on the phones with the 401 Unauthorized, so I know the phones work in that scenario.

I'm using the default ser.cfg version 1.4 as posted on iptel.org in the Optomizing RTP Proxy page.

See below. What to do?

Thanks,
Mahatma
