Summary: add_path_received() does not add transport

Initial Comment:
I use add_path_received() in a load-balancer in front of a registrar. When a request comes in via TCP, this is not reflected in the received parameter of the Path header added with the function add_path_received().

The problem is when the registrar sends an invite via the balancer to the ua. On the balancer, the value in the received parameter of the uri is set to the destination uri, but it is sent out via udp instead of tcp because of the missing ';transport=tcp'.

Suggested fix: add the transport over which the request came in tot the received paramater in the Path header when the transport is not UDP.

Bogdan,

That is the case, the balancer speaks both udp and tcp, the registrar only
udp.

I already tested by adding the parameter manually in the 'location' table
for a registered (tcp) contact. Then the request is send over tcp from the
balancer on. So the only thing missing is the addition of the transport to
the Path header.

Thanks,

Alex.

Hi Axel,

On the LB, is there a protocol change? I mean you receive TCP and forward
to registrar via UDP?

Regards,
Bogdan
