When I configured GNUGK and Asterisk on a cloud server, I got this weird situation. They work fine on LAN. I have yate softphone, polycom RPD softphone and microsip softphone in my local VMware machine behind nat. I install GNUGK and Asterisk on one cloud server with a different port.
There 2 calls succeeded, and 2 calls failed, all audio calls.
yate h323 softphone(support faststart) => gnugk => asterisk.ooh323(faststart=yes) => asterisk.pjsip => microsip softphone (this h323 → sip call succeed)
yate h323 softphone(support faststart) <= gnugk <= asterisk.ooh323(faststart=yes) <= asterisk.pjsip <= microsip softphone (this sip → h323 call failed)
polycom RPD h323 softphone(not support faststart) => gnugk => asterisk.ooh323(faststart=no) => asterisk.pjsip => microsip softphone (this h323 → sip call failed)
polycom RPD h323 software(not support faststart) <= gnugk <= asterisk.ooh323(faststart=no) <= asterisk.pjsip <= microsip softphone (this sip → h323 call succeed)
I attached two failed call logs that came from GNUGK. It seems GNUGK can not establish a h245 connection with Asterisk. Could you give me some tips on this? Thanks.
