Configuring Voxtelesys Register Authentication Trunk
Before proceeding with the next steps, you need to purchase a DID on the Voxtelesys platform.
Collect Settings for PortSIP PBX
Before configuring the Voxtelesys trunk in PortSIP PBX, you must first collect the required SIP registration details from the Voxtelesys platform.
These values are required for the Register-Based Trunk configuration in PortSIP PBX.
Step 1: Retrieve SIP Registration Details from Voxtelesys
Sign in to your Voxtelesys account.
Navigate to SIP Registrations.
Copy and securely record the following information:
Domain
Username
Password
❗Note These credentials will be used by PortSIP PBX to register to the Voxtelesys SIP trunk. Keep them secure and do not share them publicly.
At this point, no further configuration is required on the Voxtelesys side. You can now proceed to configure the trunk in PortSIP PBX.
Configure a Register Authentication Trunk in PortSIP PBX
The Voxtelesys Registration Trunk corresponds to a Register-Based Trunk in PortSIP PBX.
❗Important
The Register-Based Trunk can be configured at either the System Administrator level or the Tenant Administrator level.
If configured at the System Administrator level, the trunk can be shared with multiple tenants.
If configured at the Tenant Administrator level, the trunk is available only to that tenant.
Step 1: Create the Register-Based Trunk
Sign in to the PortSIP PBX Web Portal as a System Administrator or Tenant Administrator.
Navigate to Call Manager > Trunks.
Click Add, then select Register Based Trunk.
Step 2: Configure Basic Trunk Settings
Enter the following information:
Name Enter a friendly name for the trunk (for example,
Voxtelesys-Reg-Trunk).Brand Select Voxtelesys.
DID Pool (Tenant Admin level only) If configuring this trunk at the Tenant Administrator level, specify the Voxtelesys DID numbers assigned to this tenant.
❗Important
The tenant can use only the DID numbers in its DID pool to:
Create inbound and outbound call rules
Configure outbound caller IDs for extensions
Hostname or IP Address Paste the Domain copied earlier from the Collect Settings for PortSIP PBX section.
DID Pool Format Examples
Click Next to continue.
Step 3: Configure Trunk Credentials
Enter the SIP registration credentials obtained earlier:
Authentication Name Paste the Username copied from Voxtelesys.
Password Paste the Password copied from Voxtelesys.
Click Next to continue.
Step 4: Configure Trunk Options
Max Concurrent Calls Specifies the maximum number of simultaneous calls that PortSIP PBX can establish using this trunk.
Adjust this value based on your Voxtelesys service plan and expected call volume.
Leave all other options at their default values unless you have specific requirements.
Click Next to continue.
Step 5: Assign Tenants and DID Pool (System Admin level only)
This step is available only when configuring the trunk at the System Administrator level.
Assign the trunk to one or more tenants.
Provide Voxtelesys DID numbers to each tenant using the DID Pool.
❗Important
Each DID can be assigned to only one tenant.
A tenant can use only the DID numbers in its DID pool to:
Create inbound and outbound call rules
Configure outbound caller IDs for extensions
DID Pool Format Examples
Click OK to save the configuration.
