hi to all,
We have a customer with this equipment in HQ: 2xCCM 4.1 in cluster, 1x3845 with 3 PRI, 1xIPCC4.0(4) installed in G.711. At remote site have: 1x2821 with 3 PRI and a wan link to HQ of 512Kb/sec. The remote site have a different region that use a G.729 codec to talk with HQ. I configure in HQ router (3845) a transcoder, but I?m not sure that this can work correctly with remote agent that use G.729 codec for talk with HQ region, and I don?t know if the transcoder is used for all conversation durations, or only until the caller is connected to an agent.
Other problem is that the customer need to use a centralized IPCC also as IVR for remote branch so I suppose that the WAN link is inappropriate; how much bandwidth for a call is needed?
Someone can tell me what is the best solution for my infrastructure?
thx a lot
