Hello, basically we recently instituted a SIP telephony system. Now we have not upgraded our phones yet so the phones are not working through IP but each phone system at the remote and main locations are working through SIP.
Basically at location A I have the main telephone system. The telephone systems at B and C have their own external lines, or go through our Metro-Ethernet Circuit in order to extension dial from telephone system B to telephone system A. The problem I am having is that calls are getting dropped because of shared internet traffic.
Is there a way that I can put in QOS statements on the routers at location B and C to prioritize all traffic coming from their respective telephone system and to their respective telephone system (From A) so that calls will not drop or lose voice signal.
