Hello, I am attempting to write a script to launch a callback based on a dial-in service. I have created this call file: --------------------------- channel: IAX2/user@voipjet/011_valid_number maxretries: 3 retrytime: 5 waittime: 5 context: dialtone extension: 912125551212 priority: 1 --------------------------- Where I first attempt to dial the callback user (channel) and then connect the call to the number they dialed (extension, which is valid for connecting via the dialtone context), I get the following error: --------------------------- -- Attempting call on IAX2/user@voipjet/011_valid_number for 912125551212@dialtone:1 (Retry 1) -- Call accepted by 216.118.117.46 (format ulaw) -- Format for call is ulaw -- Hungup 'IAX2/voipjet/1' Dec 16 12:41:17 WARNING[20464]: app_queue.c:340 changethread: Can't change device with no technology! Dec 16 12:41:17 NOTICE[20464]: pbx_spool.c:234 attempt_thread: Call failed to go through, reason 0 --------------------------- If I change the voipjet to an internal SIP extension (ie - SIP/1000) it works fine. How do I get this working? Jason
