Hi Benjamin thanks a lot for your complete response first of all, I think when we wanna eliminate Mobile Switching Centers and transmit subscribers multimedia data ( voice calls and etc) by packet switches rather than circuit switch, we MUST provide some degrees of QoS for the connection. base on 3gpp standard, IMS used diffserv and mpls to provide QoS for users based on type of connection (conversational, streaming, interactive & background) and based on user’s charging type(Gold, Silver …). I don’s see anything about diffserv and mpls in cw docs.
secondly, we’re gonna deploy CW IMS for university(Isfahan University of Technology) and there must be some reasons (like QoS) to prefer CW IMS to some VOIP servers like Freeswitch. thirdly, we have implemented EPC by Open Air Interface open source and we’re gonna connect CW IMS to it but as you now, Metaswitch Perimeta is not open source, so we’re looking for an alternative. It seems that you know how we can overcome this problem (eg. an alternative open source) _______________________________________________ Clearwater mailing list [email protected] http://lists.projectclearwater.org/mailman/listinfo/clearwater_lists.projectclearwater.org
