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.
