hi:

I installed ser-0.9.6 on centos 5.

I start ser use ser -D -E.

ser -D -E
Listening on
             udp: 127.0.0.1 [127.0.0.1]:5060
             udp: 121.14.136.107 [121.14.136.107]:5060
             tcp: 127.0.0.1 [127.0.0.1]:5060
             tcp: 121.14.136.107 [121.14.136.107]:5060
Aliases:
             tcp: localhost:5060
             tcp: localhost.localdomain:5060
             udp: localhost:5060
             udp: localhost.localdomain:5060

When i registered with sip ua but the "SIP registration failed, status=408 (Request Timeout)" return.

The annex is the ser.cfg file and tested result with sipsak.
