What's the bandwidth requirement for VOIP? Can our old PBX be integrated with Cisco Call Manager?
The bandwidth depends on the type of compression chosen, but is typically around 64k per call. As for integration from your PBX with Call Manager, there are several that will integrate, allowing you to phase in a full VoIP system. However, not knowing which PBX you are using, I can't really say. However, your local Cisco rep can certainly assist you with this request. I am happy to put you in touch with yours if you can provide me your location or you can find them on the Cisco website.
