A system in TMS is not given the choice to call out an H.323 Gateway. Why?

Q. A system in TMS is not given the choice to call out an H.323 Gateway. Why?

A. To make H.323 calls out an H.323 Gateway, TMS must know the system has IP Bandwidth, is registered to an H.323 Gatekeeper, and that the assigned IP Zone has Gateway prefixes defined.

1. Check the IP Bandwidth:

1. Go to Systems > Navigator.

2. Select the system.

3. Click the Settings tab.

4. Ensure that Maximum IP Bandwidth in the Call Settings pane is greater than 0. (If not, and you have the necessary permissions, click Edit Settings, enter the bandwidth and click Save.)

2. Check Gatekeeper Status:

1. For the requesting system, go to Systems > Navigator.

2. Select the system.

3. Click the Settings tab and scroll down to the Network Settings pane.

4. Ensure that H323 Call Setup Mode is Gatekeeper and that Gatekeeper Registration Status is Registered.

3. Check IP Zone configuration:

1. Still in the Settings tab, under the General pane, note which IP Zone is associated to the system.

2. Go to Administrative Tools > Locations > IP Zones.

3. Select the IP Zone that's associated to the system and use the drop-down menu and select View.

Gateway Auto Prefix is used for H.323 video calls.

Gateway Telephone Prefix is used for telephone calls.

If no prefix is defined, TMS will not offer H.323 ISDN calls for systems associated with this IP Zone.

When attempting a call using Scheduling, the TMS Scheduling Settings of each system are also taken into account. Each system has an allow permission for incoming calls and outgoing calls for each call protocol. TMS will not offer a call route if the allow permission is not granted for the call direction requested by each endpoint in the call.
