User guide

Cisco Unified Communications Manager assumes all loop-start trunks lack positive disconnect supervision.

Configure trunks with positive disconnect supervision as ground start, so active calls can be maintained

during a Cisco Unified Communications Manager server failover.

Note

Before You Begin

You must add a VG200 gateway template before configuring ports. See the Create Cisco VG200 gateway

template, on page 356 for instructions.

Procedure

Step 1

Find the gateway template to which you want to add FXS ports.

Step 2

From the Gateway Configuration window, click the endpoint identifiers of the FXO port that you want to

configure.

Step 3

From the Port Type drop-down list box, choose either Ground Start or Loop Start.

You must choose the same port type for both endpoint identifiers of the VIC-2FXO port. If you

choose different port types, a message displays.

Note

Step 4

Enter the appropriate Gateway Configuration and Port Information settings, and click Save.

See FXS/FXO port configuration field descriptions, on page 372 for field descriptions.

Step 5

To return to the main VG200 gateway configuration window for the gateway to which you just added the

ports, choose Back to MGCP Configuration in the Related Links drop-down list box and click Go.

Step 6

To reset the gateway and apply the changes, click Reset.

Step 7

To add more FXO ports, repeat Step 2, on page 359 through Step 4, on page 359.
