Why Does an IP Phone Fail to Be Called After the RBT Service Is Enabled in an H.323 Trunk Scenario?

Why Does an IP Phone Fail to Be Called After the RBT Service Is Enabled in an H.323 Trunk Scenario?

In Figure 29-42, RouterA functions as a PBX and is connected to the IP phone of User A. RouterA communicates with the remote PBX through an H.323 trunk. After the RBT service is enabled on RouterA, User B calls User A. The call is unexpectedly released after User A picks up the phone.

If User A uses an analog telephone, calls are not released unexpectedly after User A picks up the phone.
Figure 29-42  RBT service over the H.323 trunk

The cause is that the early media renegotiation function of H.323 is disabled on RouterA. The RBT service negotiation fails, and calls are unexpectedly released.

Run the pbx number-parameter command and set the value of the 7th control point to 1 to enable the H.323 trunk to initiate renegotiation in the early media scenario.

Run the following commands:

<Huawei> system-view
[Huawei] voice
[Huawei-voice] pbx number-parameter 7 1
