Hi list, I have a call file as following and it works. But, I don't really understand its mechanism. The SIP/voipbuster is a sip trunk which I set up in freePBX with voipbuster account. And 2874 is one of my extension which was assigned to x-lite client. When I place this call file in outgoing folder, it is able to dial out my home phone at 001xxxxxxxxxx. However, the Dst in call logs show 2874 or s instead of my phone number. Why sometimes 2874, sometimes "s"? and why not my phone number? My interpretation is the call file actually "call" extension 2874 and place a out going call via 2874. If I am right, does it mean any outgoing call has to be placed through an extension. How can I manipulate this call file in order to show my home phone as destination instead of extension number. Thank you very much. Channel: SIP/voipbuster/001xxxxxxxxxx MaxRetries: 1 RetryTime: 60 WaitTime: 30 Context: outgoing Extension: 2874 Priority: 1 Thanks in advance!! _________________________________________________________________ Try the next generation of search with Windows Live Search today! http://imagine-windowslive.com/minisites/searchlaunch/?locale=en-us&source=hmtagline
