Branching v5.0
by Daniel-Constantin Mierla 09 Feb '17

09 Feb '17

Hello, following discussion on mailing lists and at Fosdem over the last weekend, I am considering to create the git branch 5.0 later this week, on Thursday, Feb 9, 2017. Afterwards, the master branch can take commits with new features. The branch 5.0 will be tested for 1-2 more weeks and if all is fine, the v5.0.0 can be released. Should anyone have other suggestions, jump into discussion.

nathelper module fix_nated_register(); question
by JR Richardson 09 Feb '17

09 Feb '17

Hi All, Just confirming when using nathelper, the fix_nated_register function is only used to write corrected contact into to $avp then to database, this function does not actually change the contact in the SIP message when passing through the proxy, correct? fix_nated_contact is used to actually change the SIP message contact when passing through the proxy. I'm using kamailio 4.2. Thanks. JR -- JR Richardson Engineering for the Masses Chasing the Azeotrope

by Switch168 09 Feb '17

09 Feb '17

Hello, Just wondering if it's possible to intercept the bye message that dlg_set_timeout sends out to do some nat_helper function to fix it so the bye can be sent to random.invalid uris. I know there is the edge proxy outbound module but wondering if I can do it without. Regular bye between 2 clients i was able intercept and fix with nat helper but I dont know how to fix the byes that is sent out from dlg_set_timeout function. Thanks in advance! Andrew

Cannot hear voice with symmetric NAT and STUN
by Khoa Pham 08 Feb '17

08 Feb '17

Hi, I have Kamailio as SIP server and RTP server. Client is PJSIP. I read that STUN is for non-symmetric NAT, and RTP server is for symmetric NAT. Supposed A calls B. If A, B both use symmetric NAT and STUN, they cannot hear each other If A or B use non-symmetric NAT and NOT using STUN, they cannot hear each other. Why is that? I read http://tools.ietf.org/id/draft-takeda-symmetric-nat-traversal-00.txt for Prediction Failure, is that related to this problem ? -- Khoa Pham HCMC University of Science Faculty of Information Technology

Diversion Header - relay messed up
by Roman Dissauer 08 Feb '17

08 Feb '17

When I get an INVITE with Diversion Header the Request is forwarded without Diversion Header and the Request User is taken from Diversion User. Problem is that on the Destination Host I cannot get original Request User what is the intended destination! Is this intended behaviour? How can I change this behaviour? I already tried to delete the Diversion Header on request_route but this didn’t change the behaviour. Thanks in andvance for your help!
