VoIP Compression

[golfrookie]

I have an Option 11C running Succession 4 and a BCM at the far end. They are connected using IP trunks. How do I find out what VoIP compression is being used on our IP trunks? If I want to change the compression, how do I do that?

Thanks,
Keith

Are you using OTM????

You should be able to check it with Element Manager.

If this Option11c is a succession or NNCS1000M it must have a signalling server. The compression algorithms are selectet there in the element manager. Standard is G711 (ISDN quality 64k per channel) and G729 (compressed 8k per channel).

The assignement is made as JP said via LD117 Zone entry.
BB stands for best bandwith (-> G729) and BQ stands for best quality (G711) you have additional to enter the total bandwith within and between the zones to allow the system to calculate when the blocking situation has reached.

The zone´s are assigned via RDB or TIE programming (sorry I can't look it up because I am not sitting in front of an system).

On the BCM side I can't tell you, because there's only a little experiance.
