We have a remote site with 4 phones that was using CME but is now on MPLS network and those 4 phones are now registered on CUCM at main site.
We have installed a BRI cards on new router with number 555-1234. The 4 phones have an extension of 34XX.
When any of these 4 phones call out the called person sees the Caller ID of 555-1234 rather than 555-34XX.
When an outbound call is made Debug isdn q931 shows correctly the calling number to be 34XX.
My first question is does BRI lines support CallerID?
If it does can someone point me in the right direction.....as in will i have to consult Telco etc
