Hello boys!

I have one problem after updating from openzap to freetdm. Now, whe FS receives 'Proceeding' from PRI sends a SIP 180 which makes the phone to play a fake ring tone. After some seconds, when FS receives 'Alerting' from PRI, FS sends a SIP 183 with the real ring tone.

Is there any way to avoid first SIP 180? If the calle is busy, I can hear a ringing tone between SIP 180 and SIP 183 and a busy tone after SIP 183. Same if calle is a mobile phone and it is out of signal.

Can you also tell us which ISDN stack are you using? we will update naturally first ftmod_sangoma_isdn, but as soon as we do that we can take a look at ftmod_libpri or ftmod_isdn if you are using those.
