Re: [SR-Users] NAT pinging after service restart

Hello again, My original post was incorrect. The nat pinging actually works perfectly on restart. It turns my issue was with the "keepalive_timeout" module param in the nathelper module. For some reason whenever keepalive_timeout is set, when Kamailio is restarted after a few seconds "Expires"

Re: [SR-Users] Parallel forking - first responder wins

It should be noted at a rather general level that parallel forking is replete with race conditions, and is a nasty and unwieldy aspect of SIP. The pain of using parallel forking to implement something like "ring groups", for example, is often not worth the savings in architectural complexity. If

Hi.. Thank you all very much for answering me. I have made many test: First, I've installed ssl cert with letsencrypt, like https://www.fredposner.com/1836/kamailio-tls-and-letsencrypt/, this one i made it before. I've configured tls.cfg like: [server:default] method = TLSv1.2

[SR-Users] INVITE forking - uniform way to identify branches

Hi all, I have a prioritised list of endpoints, where endpoints with the same priority should be sent in parallel: - endpoint_1_uri; p = 1 - endpoint_2_uri; p = 2 - endpoint_3_uri; p = 4 - endpoint_4_uri; p = 5 As some of the lower priority endpoints are not known upfront, I can not load

Re: [SR-Users] Parallel forking - first responder wins

That is the reply route. Start testing and adding logging. The case with multiple 200 OK is something we have tested many times. The proxy should NOT try to do anything in that case, just forward the multiple 200 OK to the caller and let the UA decide what to do. The UA needs to ACK both, and

Re: [SR-Users] Parallel forking - first responder wins

You are right that this is not very explicit. Kamailio will cancel automatically once one branch connects but if it failed to cancel (meaning other branches connects) The originiting UAC will have to disconnect the extra calls. Which is something that is handled properly by most if not all. On

Re: [SR-Users] Parallel forking - first responder wins

Just thought of a follow up question - is it possible to find out which of the branches Kamailio chose as the winner? According to RFC multiple 200 OK could arrive before CANCEL is sent. Do I need to look for an outgoing ACK to know for sure which branch was chosen for sure or is there a way I

Hi Ahmed, there is a lot of material related to integrating Kamailio and Asterisk. You will get useful help here by describing in detail what you want to achieve, what constraints you have, and what you have tried already. Cheers, Giacomo On Mon, 20 Apr 2020 at 01:43, ahmed moghazy wrote: >

Re: [SR-Users] How to install the PHONENUM module?

Use also "make install" inside kamailio source tree to deploy the module, rather than manual copy. Then, be sure that the location of libphonenumber library is in the path for linker and also run a 'ldconfig' to rebuild ld cache. Otherwise, it would be recommended to use the available

Re: [SR-Users] Parallel forking - first responder wins

As far as I understand, RFC3261 is not providing any instructions on how to deal with forked INVITES specifically. It just says that forking can result in multiple dialogs that are part of the same original call. I couldn’t find any prescriptions on how/when to deal with these multiple dialogs

Hi all, What I’m trying to achieve is to have Kamailio fork an INVITE to multiple endpoints in parallel but only maintain the branch that responds first (first to respond with 200 OK I guess). I’ve read the TM module documentation on forking
