[cisco-voip] CUCM6+E1 PRI g711Alaw

Hello all.

I've got a e1 pri line in my office, terminating by cisco 2821. The compand
type for E1 (Europe) is A-law, and show voice port 0/0/0:15 also tells me
that.
E1 is registered via mgcp, and i also see the compand type A-law in options
there.

When i press the question button twice during the pstn call, the negotiated
codec is u-law.

The default codec in Region is "G711" (no option for a-law or u-law)

Is there such an option in CUCM to change the default modulation type for
g711 codec?

Thank you.
