[asterisk-ha-clustering] Load sharing between two asterisk servers

[Yehavi Bourvine +972-8-9489444]

Hello,

  I know this is not a pure High Availability question, but I think it is
related...

  I would like to do  load balancing between two Asterisk servers and allow the
phones to use the other server as backup. Asterisk is installed on both
systems, the users (extensions) are defined in MySQL database (realtime
Asterisk); the MySQL database is replicated on both systems.

  What I see is that only the server to which the phone registered knows about
its location. The other server doesn't know it, and thinks that the phone is
offline (although I see its current address in the MySQL record).

The realtime section of SIP.CONF is as follows:

rtcachefriends=yes
rtsavesysname=yes
rtupdate=yes
rtautoclear=yes
ignoreregexpire=yes

I tried setting rtsavesysname=no but it didn't change the behaviour. Any idea
what I am doing wrong, or how to do it?

BTW, I tried to code  the dialplan to check the sysname field in MySQL; if it
finds that the phone is on the other server then to direct the call to there.
However, it then fails authentication (even if I set bith servers to be
"insecure") :-(

                             Thanks! __Yehavi:
