IP Endpoint Time to Service
The Time to Service (TTS) feature improves the time required to bring an IP phone system into service by reducing the amount of required signaling for a phone to reach the
There are two functions in TTS that improve IP endpoints availability. One function is that the IP Endpoint
With Avaya Communication Manager Release 4.0, the TTS separates the timing of the H.323 registration process from the timing of the TCP
With TTS, after all the IP phones within a system register to the Communication Manager, the TCP socket is established when the processor occupancy level returns to normal. However, when the main processor occupancy level is high, the TCP socket is established on demand (when users make a first call or when a call needs to be delivered to a user) or via background maintenance. Once the TCP socket is established, the socket remains up for subsequent calls. In addition, with TTS, Communication Manager, rather than the IP endpoint, initiates the establishment of the TCP socket resulting in faster establishment of TCP sockets.
The second function of TTS significantly reduce the number of times that IP endpoints need to
