Re: Webrtc connection failure on multiple kamailio server setup

You can also use the sipcapture module with sngrep:

As stated, use path to record the server that is handling the connection and route it from there.


  1.
User foo@domain sends REGISTER to server-a.
  2.
Server A saves register in a way that is accessible to both server and server B.  Included in this is the path info. The record looks roughly like this (paraphrasing, so it might not be completely accurate):
AoR: foo@domain
Contact: foo@hostname;transport=wss
Path: sip:server-a:5060
  3.
INVITE arrives on server-b for foo@domain. server-b checks the location and relays the INVITE with an RURI of foo@domain;transport=wss and sets the destination URI to sip:server-a:5060. Liekly you'll have server-b also insert itself via Record-Route as well.
  4.
server-a receives the request and relays it to the RURI

Regards,
Kaufman

No. WS is:
- TCP based
- TLS encrypted

By default you won't be able to migrate TCP sockets between different machines.

Hi Yuriy,

I understand if call goes out from kamailio1 where socket connection exists will work. But I am looking for a load balanced or high available solution where any of the instances could able to send the call out. Is it a possible scenario ?
