Is there somewhere to assign the area code on incoming SIP calls?

In 22-09-01, we can only put a maximum of 8 digits but SIP trunk provider is sending 10 digits. Does the system automatically ignore the first few digits or is there someplace we can enter the area code then program the seven digit DID in 22-11-01?

We now have three area codes so it is conceivable, however unlikely, that we could have XXX-123-4567 and YYY-123-4567.

Expected Number of Digits
Enter the number of digits the table
expects to receive from the telco. Use this
program to make the system compatible
with 3- and 4-digit DID service.
If ISDN trunks, we analyze the last digits
that are set here. If it is T-1 or analog DID,
it analyzes the first digits that are assigned
here.

I am fairly certain that if you get AAA-BBB-CCCC that you can set it for 4 and you will analyze CCCC. Not certain. That is very un-standard to send 10 digits. Seven usually in large networked systems.
