How to Obtain the Telephone Number of a MDU / OLT Device

Hello, everyone!

Telephone numbers are allocated by the MGC. Generally, no telephone number is configured on the AG (that is, the telno parameter is not configured).

If H.248 or SIP is used and the emergency standalone function is enabled on the device, you need to configure the phone number (telno parameter) when adding a user. It is recommended that the number be the same as that allocated by the MGC/IMS. In addition, this telephone number must be unique in the AG to avoid number conflict when the emergency standalone function is enabled. If this parameter is not set, the phone number is empty by default.

You can also query the existed telephone number by running the commands:
display sippstnuser  for PSTN users,
display sipprauser  for PRA users,
display sipbrauser  for BRA users,
display sipr2user  for R2 users.

Thanks.
