[Serusers] Question about SER

Hi
I've setted up a TestBed about ToIP based on SIP. In this TestBed I've
used a SER Server running on a Linux Red Hat 9.0.
I have had several problems with this TestBed for a long time. I cannot
call external phones across the gateway (Cisco 1760). Once the call is
established it lasts 20 second, before this time it hangs up.
I would like to ask you, if its possible for you to review my
configuration in order to detect any kind of mistake or problem.
Thanks for all your help
Albert
