[asterisk-bugs] [JIRA] (ASTERISK-24040) Retrieving source port of sip message in dialplan

[Matt Jordan (JIRA)]

Matt Jordan commented on ASTERISK-24040:
----------------------------------------

New features need to be written against trunk. Requiring others to do that work for your patch will delay when that patch is merged into Asterisk.

If you'd like this to get included sooner rather than later, please write the patch against trunk and make sure it compiles and functions correctly.

> 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}
