Extension Exists
Hi,
When a VOIP user dials an external number, the calls are routed through our SIP provider.
Is there a simple way to check whether the DDI exists locally before dialling out to the sip provider?
Something like GotoIfExists(5551234 at incoming_calls)
Currently, I'm paying for all calls, regardless of whether they exist locally.
All DDIs exist in the incoming_calls context.
Thanks
Dan
