G711 Codec - Does CallManager use G711alaw or G711ulaw?

Hello,

Is it possible to select G711alaw on Cisco CallManager Region settings?

Apparently the CallManager is only capable of G711uLaw with respect to this codec.

Any clarification would be greatly appreciated!

Thanks,

Erik

I'm not sure why you would need to specify a-law or u-law. You are right as the documentation and setup never specify u or a, so I assume that it does both not one or the other. Can you give us an idea of what you are trying to do?

Hi Rick,

We have an office in Australia where local telco send G711alaw. Our hunch is that somewhere a transcoder is being introduced to convert that stream to G711ula. If we could specify a-law this would seem more efficient.

Thanks,

Erik.
