we’re using Asterisk as SIP Gateway for our Lync deployment.
We want to add another SIP Provider now and have some questions about Routing.
We have to route calls from Lync to one of the SIP Providers.
Ex. if 111111-1111-11 is calling from Lync, Asterisk should route it to SIP Provider 1
if 2222222-2222-22 is calling, it should route it to SIP Provider 2
Currently, we have the following set in the extensions.conf:
;Routes with 1 followed by three digits to local extensions
;send other calls to Sipcall for Asterisk
As i see, everything starting with + is sent to the Sipcallp provider.
Is there a way to route based on sender number instead of recipient number?
