Dear list,

actually I'm searching for a solution to limit the max. simultaneous  
calls per user.
I`ve searched the internet and list-archives for possible solutions.
But until now i haven`t found a solution.

What i exactly need is to define the max. simultaneous calls per user  
(e.g. 2,4,6,8,...).
I know, that openSER is transaction-stateful, not call-stateful but  
is there a way
to monitor the number of RTP-Sessions per user from Mediaproxy and  
set the
"max_calls"-variable via an AVP?

My setup is openSER 1.2.1-notls + Mediaproxy

Has anyone implemented such a solution or anyone know such one?

Perhaps i had to place a kind of SBC/B2BUA in front of my SIP-Proxy?

Many thanks in advance,

kind regards

Sebastian
