IP Phones
The second scenario of an IP phone attached to Ubigate iBG3026 as shown in
Figure 26.5. The SIP phone communicates directly with the Call Manager
using SIP Protocol that is passed through Ubigate iBG3026. The Call
Managers communicate with each other across the IP network via SIP to
establish and maintain the call. The packets are then routed across the IP
network from IP phone to IP phone completing the connection. The second
requirement, to support IP phones connected to Ubigate iBG3026, is to
connect Ubigate iBG3026 to the PBX or PSTN enabling the IP phones to
make calls to traditional phones. In this case the IP phones communicate with
the Call Manager and in turn the Call Manager establishes the call to the PBX
or PSTN through Ubigate iBG3026. The packets from the IP phone are then
routed through DSP and delivered to the PBX or PSTN via analog or digital
trunk lines.
