Hi,

I have two Quadro 4x's connected over the internet via SIP Trunk.

To call the other office a prefix is used as defined by a call routing rule.

For best quality over the link, I wish to force a specific codec G726-40 to be used for this call routing rule only - without changing the preferred codec for all of the extensions....

How do I do this? I can't see codec preferences in the routing rules

Thanks
