Hello,<br>I'm testing FS support for the header Path (FS is behind opensips).<br>It pretty much works: I tested calling from one user to the other and calls work perfectly. <br>However, I've noticed that when I register my terminal directly with FS without going thru the proxy, I receive an unsolicited NOTIFY containing Message-Waiting information. But when I register via proxy, FS doesn't send this NOTIFY.<br>
What could be causing this difference of behavior? (enabling debug (F8) doesn't show anything for registration handling). <br></blockquote></div></div><br>I have enabled Sofia debug and I can see NTA is complaining about invalid URI when building the NOTIFY:<br>

<br>I hope someone can point out a problem.<br>
I'm looking at NTA with gdb but I'm slow on this.</blockquote><div><br>The invalid URI nta is complaining about is the route_uri extracted from the Contact stored upon registration.<br>The difference of behavior between INVITE (works) and NOTIFY (doesn't work) via proxy, seems to be because for INVITE, mod_sofia code (function sofia_glue_do_invite in sofia_glue.c) calls sofia_overcome_sip_uri_weakness to adjust the route_uri. <br>
But for a NOTIFY, this function is not called (and it cannot be called, as there's no session which is required as a parameter).<br><br>In my case I can see that basically what sofia_overcome_sip_uri_weakness does is to remove the "<" , ">" around the route_uri.<br>
I messed with the code in sofia_glue_send_notify to just remove "<" and ">" and after that I was able to receive the NOTIFY.<br>So I believe there is some code lacking in FS to properly permit UAs registering via proxy to receive NOTIFY. <br>
I might be wrong: if there is anyone using this scenario successfully, please let me know. Otherwise, I'll open a ticket on JIRA.<br><br>regards,<br>takeshi<br><br></div></div></blockquote></div><br></div></div></div>
