Subhash55...if I am reading your post correctly.
You changed dial tone service providers on you Mitel system at your Motel and now caller id is no longer working?
If you switched from Frontier Communications, AKA "Bluefield Telephone Company" to Comcast (or something variation there of) then you need to contact your new provider and let them know that you:
- Need to add ICLID, or
- ICLID is not working as ordered.
and that it worked before.
ICLID (Caller ID) is provided by the telephone company not the Mitel system.
