On the GSM gateway logging shows nothing! Using wireshark I've seen that
the gateway respons only to the three-way handshacking and after that
there's no SIP response.
As I wrote before, this behaviour happens with Grandstream and Linksys
phones and with the Zoiper softphone. If I use SJphone, the call setup
works well.
Attached to this mail you can find another trace, referring to the call
setup between SJphone and the GSM gateway.
As you can see, now the GSM gateway responds. It seems to me that the
difference is in the Proxy-Authorization entry ("algorith=MD5" missing).
The PC running SJphone: 155.185.3.3
The Sipx proxy: 155.185.3.99
The GSM Gateway: 155.185.3.247
CallId: D33B0B93CCC340659F7408F38CDB4BC00x9bb90303
Thanks,
