When using Enterprise Alternate Number (8 digits) for internal dialing, CUCM still sends caller ID as extension number (4 digits on this case). Since 4 digits can not be dial back (because overlapping) , entire purpose of Enterprise Alternate Number is defeated.
Using Calling Party Normalization also did not work since 4 digits extension overlaps AND Extension Mobility is in use.
Any idea how Enterprise Alternate Number can be send for caller ID number?
Thanks
