> I need to route calls in the dialplan based on source ip and source port. Source ip can be retrieved with {{$\{CHANNEL(recvip)\}}} but there is no entry in CHANNEL var to retrieve the port (much to my amazement). Attached is a simple patch that appears to do the job for SIP channels: {{$\{CHANNEL(recvport)\}}}:
> For 
> {noformat}
> exten => 1,n,NoOp(ip:port ${CHANNEL(recvip)}:${CHANNEL(recvport)})
> {noformat}
> a sip invite like:
> {noformat}
> <--- SIP read from UDP:10.0.3.175:5555 --->
> INVITE sip:1 at 10.0.2.16 SIP/2.0
> {noformat}
> will result in:
> {noformat}
> -- Executing [1 at default:2] NoOp("SIP/tst-00000004", "ip:port 10.0.3.175:5555") in new stack
> {noformat}
