I have an officeserv 7100 and I converted two voip extensions (213 212) to internal extensions. I added in a new 4DLM card and the other two extensions are working.

When you try to dial that ext from another one (201, 202 etc), it does not ring 213 or 212.

I checked under 2.8.0 and I see them listed as US 24B set while the others are listed as 28B SET.

The old IP phone were SMT-i6021 which show their extensions now as 3201 and 3202.
