UC500 - Inbound FXO Call Block Example?

nyciscotech

Anyone have a working CLI example of blocking an inbound FXO call based on Caller-ID?   The UC540 was configured with the default CCA config and unfortunately not having much luck getting Call Reject to work from the command line.

Thanks!

It is not possible even if you use CLI.

Any truth in the above post or does using CCA for the config disable this functionality?

You can block calls if they use a dial-peer for incoming calls (i.e...SIP Trunks or PRI).  FXO ports use a connection PLAR command which forwards the number without the use of a dial-peer.
