Hello to the list again. I have my ATA behind NAT connecting to * then calls are fwd to Cisco 2600. Calls are completing, I just cannot figure out why I don't hear any ALERTING signals from the 2600 (ringback, fast busy, SIT, etc). Audio works fine though. I'm using G711ulaw. And I don't want ATA or * to provide the false ringback so I took out ('r') in my Dial command. Existing command is as follows: exten=>_.,1,Dial(SIP/${EXTEN},20,tH) I hope somebody out there could help me on this. Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20040113/1caf4386/attachment.htm
