Can´t understand Unity


we had a Test at a customer with CCM 3.3 and Unity 4.0. This test ends a few days ago and the customer tells us that at some phones he do not understand Unity when he calls Unity and listen to his Voicemessages. We made a measurement and we see that the network jitter increases when he calls unity.

Do anyone knows this effect and have a idea.

The second thing is a mistake in the german version. At the self enrollment when unity records the name of the subsriber, the system say that you have to press the *. Thats wrong, you have to press #. So the self enrollment is skipped.

Re: Can´t understand Unity

Hallo Achim,

the second problem is indeed a defect, CSCea37834, which was fixed in Unity version 4.0.2 (I believe this problem only exists when you're using the G.711 prompts).

For the first problem, it would help to understand your test better. Are you saying that over time, some (or all?) users cannot understand the Unity prompts and messages? On every call? Are these calls from IP phones or are they coming in through a gateway?

Other considerations:

- what codec are they using

- what's the exact topology that the ip packets are taking (and are there any errors/loss along the way)

- any errors in the applications event log?

- does restarting unity fix it?
