Hamid,
If your sip gateways respond with an error when they reach capacity then
this is a fairly easy task. You would put a t_on_failure("1") just
before your
t_relay() to the gateway of choice. Something like:
t_on_failure("1");
rewritehostport("gatewayip:gatewayport");
if (!t_relay()) {
sl_reply_error();
}
You would then write a function in your script like:
failure_route[1]
{
rewritehostport("backupip:backupport");
append_branch();
t_relay();
}
This will work assuming that your primary gateway at gatewayip returns
an error if it can't make the outbound call.
I haven't used the dispatcher, so can't comment on that.

I was wondering on OpenSER and came to a
Question: How can call
routing to SIP gateways be done based on their capacity? Lets say we
have two SIP gateways each capable of handling 60 cuncurrent calls.
How could I tell openser to forward the call number 61 to the next
gateway? How would open ser know if the first gateway has free
resources (previuos calls ended), and so on.
Personally I would use the dispatcher module to distribute your
calls over both media gateways. You can always handle a failure
response
from one of the media gateways if it is full and try the next gateway.
Cheers,
Peter
