Atle,
We are ready with this except for short period thing. We are not thinking about solving that issue as it is a least important thing for us. Yes, we are looking for the feature to be added in tm module so that we can have configurable ring times for individual calls.

Hi Ranga (and Adrian)
I was just qurius on when they would be finished with the software. Failure routes is a good thing ;-)

Adrian/Atle,
We did this using failure routes. Only problem
was,
wait time ( invite timer ) for both gateways is
same
as we cant have two timers with different timeout values in ser.
See inline comments.

Hi list,
We have a setup with 2 redundant stateful SER
SIP-Servers with
accounting.
For calls to the PSTN we have 2 ISDN-PRI
gateways
connected to
different ISDN-PRI lines.
We need to implement a dynamic failover
mechanism
and load balancing.
a) Incoming calls: No problem, the PSTN switch
takes care of that
b) Outgoing calls: Both GWs are registered at both SERs; calls
are
usually relayed with
"t_relay_to_udp(x.x.x.x, "5060");" But how can I implement a quick failover
including load-distribution
between those gatways?
Load distribution may require a seperate
module/exec
script to take routing decisions. When acc is
enabled
you can query database for active calls. We can quickly check which gateway is handling how many
calls
and change the host portion of URI before t_relay.
I.e. if I receive "busy here" or no response
after a short period
after the "invite", the call should be
redirected
to the other GW.
Busy here can be easily handled in failure route. Having short duration for first call and little
longer
timeout for next call is not possible at the
moment, I
guess.
Thanks in advance for your help!
Best regards, Gerhard
