Sorry, but the scenario is somewhat confusing with the pronouns and descriptions being used
I understand that an extension has 4 different accounts associated to it and each account represents a different department.
As an example - “someone calls inbound and Dials their extension it does not show which extension the call is coming to”
“Someone calls inbound” - implies that an external caller is calling into the business.
“and Dials their extension” - how is someone able to dial their extension? Is the caller reaching an IVR and then able to dial extensions directly upon doing so?
“it does not show which extension the call is coming to” - what is it? Is it the caller’s phone not showing the destination to which the call is being directed?
“now if i call the number and dial extension 1002 it does not show the name thats on the extension.”
The above also tends to support the notion that there is an external action taken to dial some number that then allows you to dial 1002. Or, do you means something along the lines of “using my extension, I dial extension 1002 directly and 1002 fails to show my name in the display when ringing?”
The fact there are multiple accounts associated to a phone is not really relevant. It seems to be more a question about the callerID at the recipient phone/extension not reflecting a caller name (Cnam). If such is the case, then it raises the questions of the call flow and if you are calling from extension to extension directly or if it entails an external call coming in and being directed to an extension. If the latter, then it may depend on what kind of telephony service is involved,
