Configuring CID

The CID feature must be configured on both the FXS and FXO interfaces. For information about configuring this feature on the FXS interface, see "Configuring CID."

For the CID feature to work correctly, enable both CID receiving and CID sending.

Enabling CID receiving for an FXO interface

The FXO interface receives the CID. By default, it detects the CID from the PBX between the first and second rings.

To enable CID receiving:

3. Set the time for CID detection and the number of rings the FXO interface receives before going off-hook.

cid ring { 0 | 1 | 2 } [ times ]

By default, an FXO interface performs CID detection between the first and second rings, and it goes off-hook as soon as finishing the detection (cid ring 1 0).
