We solved one part of our problem. We loaded IOS 12.3.13 to the Gateway and
applied the commands recommendes in the Release Notes for cisco Unified
CallManager Release 4.2(3) =

=95 no mgcp fax t38 inhibit
=95 mgcp package-capability fxr-package
=95 no ccm-manager fallback-mgcp

Everthing works fine with G729b codec. If we switch to PCMU (G711u) we can =
make
calls from the Gatway to a phone using G711. However if I want to make a ca=
ll
to a analog phone attached to the VG224 with G711 the phone rings. I can pi=
ck
up the phone but the caller gets a ringing tone from the gateway.

Any ideas why G711 behaves like this??

Our Gateways work now with the following configuration

IOS: 12.4.8 (12.4.13 did NOT work)

Adding the following commands:
no mgcp fax t38 inhibit
mgcp package-capability fxr-package
no ccm-manager fallback-mgcp

And everthing worked.

Thanks for your help and support.
