Hi all, my setup is like this:Asterisk 1.8.2.3 + FreePBX 2.8.1 running on a Debian squeeze box connected with a SIP trunk to Vega 100 VoIP gateway, which, in turn, is connected by ISDN PRI to a POTS PBX. When a call is made to a SIP extension from POTS, it proceeds OK, and the connections succeeds. But, when the call is made in the opposite direction, i.e. from a SIP extension to a POTS extension, the latter rings, but when the receiver is picked up, no connection occurs. From the Vega logs I can conclude, that ISDN sends connect when the receiver is picked up, but the call does not proceed to SIP. Any ideas? Thanks in advance. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.digium.com/pipermail/asterisk-users/attachments/20110215/94f0f8be/attachment.htm>
