Hi Rodney,

The entire conversation is in UDP. I've attached the SIP packets from the ethereal trace.

Hi Bart Have you got the SER box doing any (TCP/UDP) protocol conversion. Ie is your phone using TCP (as * only does UDP).

I am running ser 0.9.6 on CentOS 4.2 with asterisk on the same box listening on 5065.

When I register a phone with ser, I can call XXXX@pbx.nexusmgmt.com

and

these calls are forwarded to the asterisk on a forward(<external IP>,5065). I've attached my full routing block below.

After hanging up from either phone, the BYE packet never gets

delivered.

It shows up in ethereal as being addressed to the external IP address

of

the box and it gets a 404 in reply.

When I register a phone directly with the Asterisk, I can hang up from either end as normal, so the issue must be with ser.

Any hints on how I can route the BYE packets correctly?

Thanks,

Bart...
