[OpenSIPS-Users] Max Concurrent Calls with drouting and dialog modules

[Ali Pey]

Hi Bogdan,

Does use_next_gw() in drouting module adjust the values for gw_id_avp and
gw_attrs_avp parameters?

I need to use this function if the max concurrent call limit has reached
for the current gw, then evaluate the number of concurrent calls on the
next gateway until there is no other gateways.

Thanks,
Ali Pey
