Our customer is experiencing low message volume on Unity messages when the caller came via the PSTN. Greetings and prompts are fine, as is the message level if the message was left on an IP phone. We have tried all the variations in the audio decision tree, with no luck. My question is, it seems the IP phones are running at rather 'hot' levels, relative to PSTN calls. Is it possible to adjust these levels in any way? If we can reduce these without affecting basic IP phone conversations, then we can boost the Unity wavegain to whatever it needs to be for adequate VM volume, and probably use quiet prompts to even things out. On the Unity forum, it seems like a number of people have had similar problems since upgrading to 184.108.40.206.
FYI, our current setup is:
CCM 3.1.3 (had same problem on 3.1.2c)
Phone load (7960) is a mix of 0106 and 0108
Unity 220.127.116.11, dual-switch, G729&G711, no quiet prompts
I think I am having the same problem. When a pstn caller leaves a voice mail and you retrieve it and the volume is almost all the way up on the ip phone the message still sounds very low. I am using cm 3.1.3a and unity 2.4.6.
Has anyone heard of this problem in reverse? We have had complaints of some voicemails being left that are distorted, when you listen to them it sounds like the caller is too loud so it distorts the recording.
