per the ISP I have to allow certain traffic into our cisco router for VoIP traffic, was wondering what the best approach might be?
for example i need to allow tcp/udp ports 5060 - 5061, 2427 and 2727, etc.
then they mention a QoS template and recommend queuing method C or B.
going through a lot of info i'm just getting lost and hoping someone could help
i'm guessing inbound ACLs on the external interface, but don't know what the best way to accomplish?
