Hi all

Following situation

1 dispatcher/loadbalancer getting all the inbound traffic and sending it to 3 different gateway (round robin).

The loadbalancer has no (or even very few) business logic.

Just “in” – split to different gateway – “out”

3 sip gateway doing all the business logic like auth, modifications on header, different checks, …

These 3 gateways use the same database (cluster) with routing tables and so on.

A call gets terminated to a carrier through these sip gateway.

Now I would like to implement call limiting (no of calls) by using either only dialog module or cnxcc module based on “source ip” or later on “cli”.

My problem:

A call from one source ip can be sent to the (3) different sip gateway – so not all calls are processed by the same sip gateway.

How can I ensure, that only a certain number of calls are allowed – even if they are split up on the 3 different gateway?

Or do I need to implement this kind of business logic on the dispatcher/loadbalancer?

That would not make much sense, because this is just a “stupid” machine…

Thanks for helping
