Configuring Flowroute IP Authentication Trunk
Before proceeding with the next steps, you need to purchase a DID on the Flowroute platform.
This section explains how to configure IP Authentication and Inbound Routes in the Flowroute portal so the trunk can successfully interoperate with PortSIP PBX.
Configure IP Authentication
The IP Authentication section defines which PBX is allowed to send and receive SIP traffic and provides key information used later in PortSIP PBX.
Steps
Log in to your Flowroute portal.
Navigate to the IP Authentication section.
Add the public static IP address of your PortSIP PBX server.
After configuring IP authentication, Flowroute will provide:
SIP Host for the trunk
Call Prefix
Important Make a note of the Call Prefix. You will need it later when configuring Outbound Rules in PortSIP PBX.
Configure Inbound Routes
Inbound routes define where incoming calls from Flowroute are delivered.
Steps
In the Flowroute portal, navigate to Inbound Routes.
Create a new inbound route.
Set the Route Type to Host.
In the Route field, enter your PortSIP PBX address using the following format:
Example (default SIP port):
Example (custom SIP port):
Replace
1.2.3.4with the actual static public IP address of your PBX.In the Edge Strategy drop-down list, select the SIP Proxy Host noted earlier in the IP Authentication section.
Save the inbound route.
Associate DIDs with Inbound Routes
To ensure inbound calls reach your PBX, each DID must be linked to the correct inbound route.
Steps
In the Flowroute portal, navigate to the DIDs section.
Select your purchased DID(s).
Associate the DID(s) with the inbound route you just created.
Save the changes.
Configure an IP Authentication Trunk in PortSIP PBX
To integrate Flowroute with PortSIP PBX, you must configure Flowroute as an IP-Based Trunk at the System Administrator level. Once configured, the trunk can be shared with one or more tenants.
Step 1: Create an IP-Based Trunk
Sign in to the PortSIP PBX Web Portal as a System Administrator.
From the left-hand navigation menu, go to: Call Manager > Trunks
Click Add.
From the menu, select IP Based Trunk.
Step 2: Configure Basic Trunk Settings
Enter the following information:
Name Enter a friendly name for the trunk (for example, Flowroute-Trunk).
Brand Select Flowroute.
Hostname or IP Address Enter the Flowroute SIP host:
Associated IP Addresses
Contact Flowroute Support to obtain the IP addresses for your SIP trunk.
Flowroute typically provides one or more IP addresses.
Add all provided IP addresses in this field.
Example:
Click Next.
Step 3: Configure Trunk Options
Review the trunk options.
Configure the following field if required:
Max Concurrent Calls Sets the maximum number of simultaneous calls PortSIP PBX can establish using this trunk. Adjust this value according to your capacity planning and Flowroute service agreement.
Best Practice Keep all other options at their default values unless Flowroute has provided specific requirements.
Click Next.
Step 4: Assign Tenants and Configure the DID Pool
Select one or more tenants to grant access to this trunk.
Configure the DID Pool to assign Flowroute DIDs to tenants.
Important
Each DID can be assigned to only one tenant.
A tenant can use only the DIDs in its assigned DID Pool to:
Create inbound rules
Create outbound rules
Configure outbound caller ID for extensions
DID Pool Format Examples
Single number
Multiple individual numbers
Range of numbers
Combination of ranges and individual numbers
Click OK to save the configuration.
Expected Result
The Flowroute IP-Based Trunk is created successfully.
In the trunk list, the status displays as Online. (for IP-Based Trunks, the status always shows On line).
Next Steps
The VoIP.ms Register Authentication Trunk is now ready for use.
You can proceed to:
Configure outbound call routing rules
Configure inbound DID routing
Assign outbound caller IDs
Refer to the next guide section: Configuring Outbound & Inbound Calls.
