Judging from the logs, I suspect the siproxd is the point of failure -
Ekiga never reiceives an ACK to it's 200 OK and therefore terminates
the call after 32 seconds. A wireshark/tcpdump capture of SIP from
your gateway (Ekiga <-> siproxd and siproxd <-> provider) could shed
some light onto what's going on here.

Cheers
