Hello all, Recently with a particular SIP-PBX we ran into a transfer issue. It turned out that the "Refer-To"-parameter in the REFER message was incorrect. PJSIP was using: (note the '@' in the call-ID in the Replaces=) --------------------------------------------------------------- Refer-To: <sip:7001 at mysterymachine.lab?Require=replaces&Replaces= d211351c-94f4-4661-a9dea552c3b17b79 at 192.168.71.10 %3Bto-tag%3Dbf8355e9-5ae7-4226-8c467f07f3e589cc%3Bfrom-tag%3Dc69bb8230a6542ee9b3d2c2ed0fa9b4b> RFC-3515 gives us next examples (see 3rd example) ------------------------------------------------- Refer-To: sip:alice at atlanta.example.com Refer-To: < sip:bob at biloxi.example.net?Accept-Contact=sip:bobsdesk.biloxi.example.net&Call-ID%3D55432%40alicepc.atlanta.example.com > Refer-To: < sip:dave at denver.example.org?Replaces=12345%40192.168.118.3%3Bto-tag%3D12345%3Bfrom-tag%3D5FFE-3994 > Refer-To: <sip:carol at cleveland.example.org;method=SUBSCRIBE> Refer-To: http://www.ietf.org As can be observed, the '@' is escaped in above example. I've attached the diff-patch against the trunk (but can also applied unmodified into 1.x branch). While PJSIP has some standard escaping routines (pj_strncpy_escape), I found it introducing too much complexity in that particular code. So I just do a simple buffer-copy while replacing the '@' when found. With regards, Eize Slange -------------- next part -------------- An HTML attachment was scrubbed...
