SIP Extensions

Registers the Metaswitch virtual handset subscriber's SIP credentials in CCaaS so the contact center can handle calls through the platform.

Registering a SIP extension for Metaswitch uses the same virtual handset subscriber created for Target Platform, plus SIP credentials obtained from that subscriber's Connection tab in the MetaView Web Portal.

Accessing SIP Extensions

SIP Extensions is accessible to accounts with Admin permissions.

Navigate to Admin (System) > SIP Extensions
All registered SIP extensions are listed on this page

📘
Target Platform Must Be Configured First
Target Platform must be configured before registering an extension.

Obtaining SIP Credentials from Metaswitch

Open the virtual handset subscriber created for Target Platform in the MetaView Web Portal
Select the Connection tab and note the SIP Password

📘
Not the EAS Password
This SIP Password is distinct from the EAS Password used for API Information under Target Platform.

Registering the Extension in CCaaS

Navigate to Admin (System) > SIP Extensions
Select +
Enter the following fields:

Field	Description
SIP Extension	The extension of the virtual handset subscriber
SIP User	The subscriber's phone number
SIP Password	The password noted above from the subscriber's Connection tab

Registration typically completes within a few minutes — the extension shows as Registered once successful

⚠️
High-Volume MLHG Routing
A single virtual handset supporting 20 or more MLHGs requires additional extensions — each additional extension can handle up to 20 MLHGs, with traffic pointed at the 2nd, 3rd, and further extensions rather than the first. This does not apply below 20 MLHGs.
