Added an extension using template “grandstream”, template grandstream has GXP2200EXT-1, within it’s config and we have a few BLF’s.
In EPM - Mapping, we select the expansion module 1 for that extension, and select GXP2200EXT-1.
Brand, phone model, template all confirmed with GXP-2170 and GXP2200-EXT-1.
Rebuild and update, didn’t work, erased phone, didn’t work.
Verified the CFG file for the MAC does include the names of the people typed into the BLF buttons on the extension.
One more note: We were able via web interface of the phone, to add a BLF, name and number and it works.
