[Serusers] 503 Service unavailable processing

[Gregory Sandul]

Hi all.
Did anyone implemented ser processing 503 responces
from gateways?
I mean you have 2 or more PSTN gateways. First you try
to contact PSTN number trough gateway A, if there are
no available resouces on gateway A second gateway B is
contacted and call is processed on it. I just want to
know if it is possible to do it with ser.
And is it possible to implement some kind of load
balansing on a few gateways.

Regards,
Grigore Sandul.
