I'm running into a situation where I have a user that will be using IP Communicator over a low speed WAN link. I use the g.711u codec primarily for everything, MoH, IP Phones, etc. It is just this user (at least for now) that with the speed of their connection g.711u is not good. I am running CUCM 6.01 and an h.323 gateway (Cisco 3745). What I'd like to do is to have calls that go out to DN 1007 use the g.729 codec instead, hopefully this will enable him to use IPC with the lower speed. Any ideas on how I would accomplish such a feat? I'm sure it will require some modification on both the CUCM side as well as router side. Thanks for the help.
