Very inconsistent calls
by Wilkins, Steve 12 Feb '18

12 Feb '18

Hello, I have found that calls are very inconsistent. I use Kamailio 5, Asterisk 14. When certain Providers like (Sorenson, ZVRS) make calls into a WebRTC client (tryit-jssip), sometime the calls stay up until I close them (10-15 minutes), others times those calls drop in 30 seconds. This is extremely confusing...does anyone else experience this type of behavior? -Steve

t_suspend usage in branch_route
by Aymeric Moizard 09 Feb '18

09 Feb '18

Hi, I'm trying to use t_suspend in my kamailio.cfg from a branch_route. I'm using kamailio 5.1.1 on debian jessie from http://deb.kamailio.org/kamailio51 >From the documentation: http://www.kamailio.org/docs/modules/5.1.x/modules/tmx.html#tmx.f.t_suspend i can see that "This function can be used from ANY_ROUTE ." However, the INVITE is still forwarded for this branch. So obviously the "outgoing transaction" is not suspended. May be "t_suspend" is only suspending "incoming transactions"? I tried to call "drop()". This prevent the INVITE from being sent. But in such case, i have an answer is sent immediatly to the caller (SIP/2.0 500 I'm terribly sorry, server error occurred (6/SL)) I want the script to wait as expected after my "t_suspend". And in the block indicated by t_continue, i want to append a new branch. Any way to do this? Otherwise, do you advise me to control the list of branch before t_relay? I guess I can access the list. Not sure how.. so if you have any tips... Tks Aymeric -- Antisip - http://www.antisip.com

I: - w_ro_ccr(): Unable to find dialog and cannot do Ro charging without it

Hello Everyone, I've been resolved the problem.

Regular exepression issue in permissions module
by Paulo Ferreira 09 Feb '18

09 Feb '18

Hi list, I'm testing permissions module with kamailio 5.1.1 and I was struggling with regular expressions in trusted requests part of module. I noticed that 9[0-9]{4} doesn't work as expected so I had to change it for 9[0-9][0-9][0-9][0-9] to work. Is it supposed to be like that? Is there other way in this module to simplify the expression since it is not accepting the POSIX way?

Using t_relay_to_tcp()
by Wilkins, Steve 08 Feb '18

Hi All, Some providers only allow tcp so I switched from t_relay to t_relay_to_tcp(); however, nothing now gets relayed. Has anyone else had luck switching? Thank you, -Steve

Random 'BYE" sent?
by Wilkins, Steve 08 Feb '18

08 Feb '18

Hello All, I am running Kamailio 5 and using Asterisk 14 as PBX. I have a strange issue. When I receive calls from some providers to a WebRTC client, calls hang up after about 25 seconds. This does not happen with all providers and does not happen with WebRTC client to WebRTC client calls. It appears the "BYE" is coming from Kamailio. Any ideas? Thank you, -Steve
