I am specifying the contact on my legs to use the host name as I am using TLS. I set the contact for a leg to 'sip:full.host.name:5061;transport=tls' (the system I am integrating to does not like 'sips' so I have to use 'sip'). On call setup when a PRACK arrives with route headers, StatelessProxy fails to match the route against a leg as it only checks for address and port, resulting in it treating it as the next hop and sending the message to itself:
Net::SIP::StatelessProxy::__forward_request_getleg[389]: no legs which can deliver to full.host.name:5061 (route)
The following patch adds a lookup against contact to resolve this issue.
