Example: sip:[email protected]
Configure the mobility prefix on the Avaya 3100 Mobile Communicator Gateway configuration
tab as the incoming prefix for call termination. Configure the Service DN field on the Avaya
3100 Mobile Communicator Gateway configuration with the service DN.
Universal Extensions
An Avaya CS 1000 Universal Extension (UEXT) represents each mobile client instance.
The Primary DN of the UEXT determines the user’s published addresses: both private
electronic serial number (ESN) and public direct inward dialing DID (for example, Primary DN:
4680 contributes to the ESN address 8474680 and DID address +15066404680).
The mobility prefix is a prefix to all mobile user identities on the UEXT target DN. The mobility
prefix provides a digit sequence that is unique within the SIP domain to identify a mobile client
that does not conflict with the existing dial plan and routing configuration for their CDP and
UDP numbers.
The Target DN of the UEXT extends the user’s incoming calls to mobile clients that are
accessible through SIP domain. A typical setup would be AC1 + (mobility prefix) + the user’s
ESN number (for example, Target DN: 65553435335).
Important:
It can be necessary to increase the Forward No Answer (FNA) timeout for mobile client
users. The UEXT extends all calls to the Avaya 3100 Mobile Communicator Gateway. The
Avaya 3100 Mobile Communicator Gateway then presents the incoming call to the Avaya
3100 MC - Client clients over the cellular data channel of the Avaya 3100 MC - Client (using
HTTP or HTTPS).
It can take a few seconds for the data transmission to reach the client depending on the
current state of the mobile phone. If the FNA timeout is too short users do not have
reasonable time to (potentially log on) and answer the call before the call server invokes
FNA and sends the call to the FNA destination.
Caller ID table
All Avaya CS 1000 telephones use the Caller ID table. The Caller ID table is required for the
Avaya 3100 MC - Client to correctly build the Caller ID (CLID) for both Private network and
Public network calls from a number or extension.
Outgoing SIP calls from the Avaya 3100 Mobile Communicator Gateway on behalf of the
mobile client use the CLID table configured against the Multiple Appearance Directory Number
