You need to have an exten entry that matches the number of digits the
telco is sending. You should be able to see this vrom the CLI with a
couple of verbose flags.

When we had a E&M wink T1, the telco sent 4 digits of the phone number,
This meant our exten line looked like;
exten => 9004,1,answer

Now we have a PRI with full 10 digits passed and have the following
exten entry;

exten => 6152389004,1,answer
