Hello, I'm forwarding registrations to Freeswitch and adding a Path header using add_path_received() for endpoints behind NAT. When TCP is used, this results in a header like this: Path: sip:a.a.a.a:5070;lr;received="sip:b.b.b.b:35430;transport=tcp"
Freeswitch doesn't like the transport protocol inside the quotations and refuses to route a call to the registered user.
Constructing the header manually without the quotes such as: append_hf("Path: sip:$Ri:$Rp;lr;received=sip:$si:$sp;transport=$pr\r\n"); solves the problem.
Is there a reason for the quotes?
Best Regards, Spencer

without the quotes ;transport=tcp would become param of the path uri.

I see. FS complains about no transport protocol and gives a 503 with a header like that. Shouldn't they default to UDP in the absence of a transport parameter? It seems they are not honoring the quotes.
In this setup Kamailio handles NAT traversal and forwards the registers to Freeswitch. This works: Path: sip:a.a.a.a:5070;lr;received="sip:b.b.b.b:5185;transport=tcp";transport=udp
This does not: Path: sip:a.a.a.a:5070;lr;received="sip:b.b.b.b:5185;transport=tcp"

Hello Spencer,
actually double quotes are not allowed in URI parameter. In the BNF grammar the allowed chars in the "unreserved" definition are "alphanum" and "mark", where "mark" is only "-" / "_" / "." / "!" / "~" / "*" / "'" / "(" / ")" ).
This is already fixed in 3.3.0 if I am not mistaken, please check http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=a5b181bc... - maybe that helps you with your FreeSwitch.

Hi Andrew,
Thanks for the info. Yes that seems to fix the problem.

Hello, Any chance of getting this fix back ported to 3.2 branch?

Hello,
I cherry-picked the commit to 3.2 branch. Pull the last version and see if all is ok.

Hello Daniel and Andrew, Sorry to dig up an old thread, but I'm just now getting around to a more permanent fix for this. Is there a way to urlencode the received parameter?
See: http://jira.freeswitch.org/browse/FS-4989
Thanks in advance, Spencer
