As someone who has not programmed in many a year I am sure it is a mission. However, I think it is a crucial requirement in any IP phone system that will use low speed inter site links.
Asterisk has a concurrent call limit on its trunks which go some way towards making it usable. In commercial world all products we use have quite well developed admission control. The thing is, when you create QoS queues in your routers, you are creating guaranteed throughput from your PBX onto the WAN, but your PBX has to know that it has X bandwidth, or only can make X calls (based on your calculations in turn based on codec choices) so that it will never try to over commit the link. For us it would be a deal breaker not being able to use get admission control. Does the commercial version have admission control? I remember when I looked at SipXpbx about 4 years ago, it had no SBC, gateways were virtually unusable and there were so many rough edges I left it alone. Now it is polished and for the most part working wonderfully well. I am confident this key feature will end up in SipXecs. -- Regards Mark Dutton _______________________________________________ sipx-users mailing list sipx-users@list.sipfoundry.org List Archive: http://list.sipfoundry.org/archive/sipx-users/
