> 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.
