HOWTO Multi-User Extension

What is a Multi-User Extension?

A Multi-User Extension is used for connecting another PBXware or a third-party PBX to our PBXware. It can be compared to a Trunk as it is very similar.

Authentication Methods Used for Connection

Two authentication methods can be used for a Multi-User Extension:

• Registration Method
• IP Authentication Method

Requirements Before Setup

Enable a Multi-User Extension in the license

• To do so, please contact your account manager.

Allow IP Authentication on Tenants (if wanting to use IP auth)

• To do so, please navigate to the following path:

For Multi-Tenant Edition:

'Master Tenant' → 'Tenants' → Edit 'Tenant' → ‘Features’ section → 'Allow IP Authentication for Extensions' → Set to ‘Yes’

For Contact Center Edition:

'Settings' → 'Servers' → ‘Features’ section → 'Allow IP Authentication for Extensions' → Set to ‘Yes’

Create a Dedicated Extension

For more information, please refer to this link:

NOTE: ‘Enhanced Services’ should not be enabled on the Multi-User Extension.

Create a Dedicated DID

For more information, please refer to this link:

https://wiki.bicomsystems.com/en/PBXware/PBXware-6-MT-Administration-Manual/DID

After the creation of the DID, edit the same on a Tenant level and set the ‘Destination’ & ‘Value’ fields as shown below:

• Destination → Set to ‘Multi-User’

(Select box)

• Value → Set to a dedicated Multi-User Extension

(Select box)

Registration Method

When setting a Multi-User Extension by using a registration method, a user should navigate to the following path:

For Contact Center Edition:

'Home' → 'Extensions' → Edit dedicated 'Extension' for a Multi-User

For Multi-Tenant Edition:

'Tenant' in question → 'Home' → 'Extensions' → Edit dedicated 'Extension' for a Multi-User

The following needs to be set on the Multi-User Extension:

• Username
• Secret password

NOTE: All mentioned information set on a Multi-User Extension above must be set in the same way on the remote side as well.

Further, it is very important to set the following on the remote side:

• FROM USER: Must contain the Tenant number & Extension number

For a proper caller ID to be sent from the remote side, it needs to be sent through:

• RPID (Remote-Party-ID)
• PAI (P-Asserted-Identity)

More about RPID

The Remote Party ID (RPID) header field enables popular services as well as some regulatory and public safety requirements.

These services include the following:

• calling identity delivery
• calling identity delivery blocking
• tracing the originator of the call

More about PAI

The P-Asserted-Identity (PAI) and Privacy headers are defined in RFC 3325. The P-Asserted-Identity contains the caller ID information for the call on the INVITE SIP packet. The Privacy header contains information on which parts of the caller ID are private.

IP Authentication Method

When setting a Multi-User Extension by using an IP authentication method, a user should navigate to the following path:

For Contact Center Edition:

'Home' → 'Extensions' → Edit a dedicated 'Extension' for a Multi-User

For Multi-Tenant Edition:

'Tenant' in question → 'Home' → 'Extensions' → Edit a dedicated 'Extension' for a Multi-User

In order for an IP authentication to be set correctly, a user should populate the suggested fields in the following way:

• Incoming IP addresses (new line separated) → Set an IP address from the remote side

[(0-9)]

• Insecure → Set to ‘port,invite’

(Select box)

• Host → Must contain the same IP address set in the ‘Incoming IP addresses’

[(0-9)]

Further, for a proper Caller ID to be displayed, the following needs to be set on the Multi-User Extension as well as on the remote side:

• Trust Remote-Party-ID → Set to ‘Yes’

(Options button)

• Send Remote-Party-ID → Set to 'Use Remote-Party-ID'

(Select box)

Here is another additional needed field on the Multi-User Extension:

• Set Caller ID → Set to ‘No’

(Options button)
