P2P fails to call a public network endpoint after the TE40 registers with the
1. If the endpoint does not register with the
GK, the P2P can call the public network endpoint normally. Therefore, the fault is not caused
by the network between the endpoint and the public network.
2. A P2P call fails after the endpoint
registers with the GK. Then log in to the SMC web system. On the SC details
page, you can find that Allow unknown
calls is set to Yes.
3. Capture the signaling packet of the P2P
call on the terminal.
According to the above captured packets, the following information
is displayed: An ARQ request is sent to a public network terminal 112.126.x.x
The preceding log analysis shows that: The ACF SC sends its IP
address to the initiating terminal. Then, it initiates a call to the SC directly.
However, the SC network segment cannot communicate with the public network. As
a result, the call fails because the SC fails to call the public network.
4. Check the configuration of the H.323 parameter on the SC details
page, it is found that the signaling routing policy is set to Forcible. After changing the routing
policy to Auto or None, the problem is resolved.
the SC routing policy to Auto or None.
