Hi; My system is working well when using internal extensions and a broadvoice line to external calls. Today i got a DID line from DID World Wide and i probabilly missed something during the setup because when somebody calls, looks like the PBX get the call but... there is no audio. Here is the log lines, every time i call the DID number, one line like this will be created: 17:27:21.398 Endpoint::findSource [CM010001] Line configuration does not allow identification of the source of this call. Check Advanced Options for Gateways and Providers and match a field to a correct value from the following: Contact IP: '204.XX.XXX.XXX'; From: 'XXXXXX2001'; To: 'XXXXXXXX4700'; Rline: 'XXXXXXXX4700'; Contact: 'XXXXXX2001' The Setup: Under "General/General Settings/Settings for Direct SIP Calls" I have the "Local SIP domain" set to "sip.mydomain.com" (my real domain) and the "Allow calls to external SIP URIs" uncecked. To create a line i we to "Add DID", I entered the DID number, and set the options: Source: Anywhere Route calls to: "Digital Recepcionist" (office hours and outside office hours). On the DID World Wide Control Panel i have: Map to Custom Server: sip.mydomain.com Protocal: SIP Where am i missing in here? I really appreciate any help.
