Hi, we just recently started deploying Unity 3.1.5 replacing our installed base of Avaya UM users. We decided to use Unity's GSM codec to save on Exchange storage and the portability of the voice message. The cost of the disk space wasnt the problem; it was more the time to backup the increased storage amounts.
We also have a large installed base of Octel voice servers (+10,000 accounts). So, we need to be able to exchange voice messages between Unity and Octel. The Octel support folks do not want to use AMIS and they only offer Octelnet.
We purchased the Unity Bridge with the expectation that we would be able to connect the Unit Bridge to the Octel voice server and use Octelnet to exchange voice messages.
The problem we ran into is with the support codecs on the Unity Bridge. The bridge only supports 711 or 729a.
We really do not want to change the codec on Unity, because it is meeting our needs. However, I need to find a resolution to connecting Unity to the Unity Bridge. I am thinking that I can configure the FXS ports that I will be using to connect the Unity Bridge to the PSTN for connecting to the Octel voice server in their own region that uses 711 and then use my 6608 modules to transcode between GSM and 711 codecs. I have plenty of 6608 capacity, so I can easily set up a couple ports as transcoders.
Does anyone know if I can transcode between Unity and the Unity Bridge?
The limitation isnt between the Bridge and the Octel; its between the Unity and the Bridge.
In your case the message recorded in Unity is encoded using GSM. That message is sent to the Bridge as an email attachment. Then the Bridge needs to decode the message and transfer it using a normal analog phone call. The problem is that the Bridge can only decode g.711 and g.729. Therefore you arent even going to get an analog call.
Basically you cant get around recording the messages with g.711 or g.729.
Yeah I brought up support for GSM once before. I don't believe it has been road mapped though.
