I am having problems with a configuartion at our north american office.
We can dial out no problems we can dial internal with no problems we have dial peers to remote office that work correctly but....
We can not get incoming calls to ring phones.
If we enable AA, the AA answers and takes the call. When we diasable AA the calls are not matched to the appropiate dial peer.
see config fragments below.

## Note actual pattern number has been changed for security reasons however the last two digits 6. are valid;
i.e. the number an outside user would dial when dialing the offfice is
123466 or 1234567866 or 1234567891266 depending on whether the caller local, national or international ##

As such we would expect any incoming call to be translatted to 66

In summary
This phone failes to ring when any external call comes in ?
Why is this? what am i doing wrong?
