Asterisk don't send the "180 Ringing" SIP message to the calling phone when the called party is ringing. How can I force asterisk to send the ringing messages? The option 'r' in the Dial() command or the Ringing() command didn't solve the problem. Mirko

The SIP channel sends 180 ringing when we get a ringing state from the PBX core. When you request help, please also state your platform and version of Asterisk. /Olle

In this case the driver does not send the ringing. Anyway, I don't think this behavior is correct because it breaks other protocols. E.g. if two Asterisks use SIP for their interconnection and talk H.323 with foreign gateways, then the H.323 conversation produced by the conversion H.323 <-> SIP <-> H.323 is wrong because the ALERTING of the first H.323 leg won't be generated on the second leg. And according to the H.323 recommendation ALERTING is a mandatory message. Michael.
