NVoip SIP Trunk does not route DID numbers to distinct digital receptionists

[rlaraujo]

I'm using a Cloud 3CX Startup Pro 20 license and I have a SIP trunk with nVoip with 03 DID numbers.

I configured the main number (BR) of the trunk in the format 55XXXXXXXXXX and added the Cleveland and Porto numbers in the DID in the same format.

In Call handling, I set the DID numbers for 3 different digital receptionists. But, the calls are being delivered to a single digital receptionists, the same as the DID BR number

Hi @rlaraujo

In the NVoip user guide it is mentioned you need to contact Nvoip and ask them to present the called number to the RURI : User Part and To : User Part SIP fields. Did you do that?

To ensure calls are routed correctly in the 3CX PBX you must contact Nvoip and ask them to present the called number / DID to RURI : User Part and To : User Part SIP fields. These are the fields used by the PBX to match the Incoming call to a DID that is assigned to your trunk.

Yes. I contacted the support team of the Nvoip provider, provided the official documentation for the integration of 3cx with Nvoip and requested that the called number be presented in the fields:
RURI: UserPart
To : User Part SIP.

And their answer was that this setting is not possible in 3CX Startup Pro, it is only available for 3CX Pro version.
Which to me doesn't seem to make sense...

Is it possible that you send us more details on how this Nvoip configuration works so that the PBX 3cx performs the routing to the correct digital receptionist?

The option from NVoip's side should be done regardless on what 3CX version you are using. The template is the same for all 3Cx versions and so is the requirement.
3CX will read the inbound number from a specific SIP header which is set in the template and since the template is the same the same settings are needed in all 3CX versions.
