             Summary: Retrieving source port of sip message in dialplan
                 Key: ASTERISK-24040
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24040
             Project: Asterisk
          Issue Type: New Feature
      Security Level: None
          Components: Channels/chan_sip/NewFeature
    Affects Versions: 11.10.2
            Reporter: dtryba
            Severity: Trivial


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 
exten => 1,n,NoOp(ip:port ${CHANNEL(recvip)}:${CHANNEL(recvport)})

a sip invite like:
<--- SIP read from UDP:10.0.3.175:5555 --->
INVITE sip:1 at 10.0.2.16 SIP/2.0

will result in:
-- Executing [1 at default:2] NoOp("SIP/tst-00000004", "ip:port 10.0.3.175:5555") in new stack
