Hi,
We have two locations lets say A & B, for which the end-to-end delay is about 150 ms. If A has two endpoints (say A1, A2) and in B another two (B1, B2), and if we were to try a multipoint call between 3 of the endpoints, it seems that it is not possible to achive the recommended end-to-end latency of <200ms for all the call legs of the multipoint call, since
If the CTMS is placed at site B, then A1 to A2 latency will be 150+10+150
if the CTMS is placed at site A, then B1 to B2 latency will be 150+10+150
Is there a solution for this ?
Thanks

For MP meetings the latency measured by each participant CTS is only a measuremen of the latency from CTMS to that EP
Its possible for the end-to end latency from one CTS through the CTMS to another CTS to exceed 250 ms as n your case but CTS wont realize, CTMS is the only device that is aware of this end-to-end latency.
When we have the MP Call, audio and video RTP packets timestamps s re-written by CTMS therefore the latency meausred by each particpant. Os its possible that end-to-end latency exceeds, but TP system will never realize so its ok.
