Caller ID on call forwarding

[NBX_Tech]

Suddenly my system is no longer forwarding the caller ID of the person calling, when the extension is setup for call forwarding. If it is a user calling from within the PBX it does forward the Caller ID information, however it does not when the call is coming from outside. I've looked and I cannot find a feature setting for this. Does anybody have an idea of why this may be happening?





One other note, we recently switched ISDN carriers from Level 3 to Verizon. Would the carrier restrict this type of service somehow? Thank you.

Its very possible .

When was the switch ? Before or after the issue started ?

what kind of NBX ?

What code ?

What types of tels ?  31XX , 21XX , 11XX , etc .

When a regular call comes into a tel , does the correct caller id show up prior to transfer/ forward ?

Yes, caller ID works great on incoming calls to the phone.

I take it you are call fowarding a call back out the ISDN lines.. so a call comes in the ISDN line and then gets forwarded out another line.. is this the scenario?

If so, then check Country Setings/Advanced Regional Settings, setting should be "Send Originators Caller ID"..

If it is set to that, that means you telco is changing it... many telcos may see a caller id coming out the PRI line which is not what they expect (it is the originators caller id) and change it.

Go to the carrier and ask to see what they see on an outbound all forwarded by us .

You can also do stk logging on the NBX and we can see what is being sent . You can open a case for instructions on this and we would be glad to assist .

Not sure why but it may be we are presenting something to the carrier that they do not like , in the string .

One option is to go into regional settings / advanced and see what that is set for . You may want to try and change it and see if this resolves the issue as well .
