Failed to join a conference by dialing the Ad Hoc number or Unified Access number

Hi, dear!

Welcome to the community!

The process of dialing an Ad Hoc number or a Unified Access number is as follows:

The SC receives a call > Report the event to the SMC and request the called MCU > The SMC sends a response to the SC and notifies the SC of the MCU alias (SIP URI or H.323 ID) > SC Search for the called party.

So, if the call fails, check the MCU allocated by the SMC to the SC in the response.

1. View the SMC2.0 system log. You can find the MCU allocated for the IVR call. Assume that the allocated MCU is 5.107_MCU.

2. In the MCU list, check whether the MCU is registered with the SC to which the calling terminal belongs.

• If the MCUs are not on the same SC, configure a search rule to specify the SC. The search rule must match the alias of the MCU, that is, SIP URI or H.323 ID, instead of the original ad hoc number or unified access number. 

• If the MCU is registered with the SC and the SIP URI or H.323 ID (determined based on the calling protocol) of the MCU is displayed in the registration list of the SC, check whether the called number is changed or whether the called number is routed to another device due to a rule.
  

Best wishes!
