[Freeswitch-users] Call limit on RTP-IP Address

Hello all, If we assign more then one RTP-IP parameter to a sip profile , they are used in round robin. Its perfect . I want to know is there a way to use some limit on that ip ? Say i've 5 ip address listening on box , and i want one concurrent call limit on each media ip. How can i set limit on profile level or set from dialplan. I tried to do but it didn't work . Any help or advice will be highly appreciated Thanking all Nabeel.
