Conditions
It is recommended that this feature use ISDN/SIP platform (as these trunks provide answer
supervision).
If the extension has Call Forward-Both Ring set to a Mobile Extension (twinning), it can only
forward to VM (NA or B/NA) and nowhere else.
If an extension has Call Forward-Both Ring set to a Mobile Extension (twinining), it will not
forward when the Mobile Extension is forwarded All or B/NA (Busy Immediate).
Analog, ISDN and SIP trunks are supported for the outbound call to the Mobile Extension
The analog line must provide calling line identification information to allow the Mobile
Extension to dial into the system to access features.
For the extension DTMF, the minimum Detect Level for the DTMF Tone (Program
80-03-03) must be set to allow a minimum detection level of -25dBm. This entry is
dependent on the Detect Level selected in Program 80-03-01.
The Mobile Extension uses the * to perform a flash, so any service codes which begin with
* must be changed (Programs 11-10, 11-11, 11-12, 11-13).
To provide a proper disconnect, Disconnect Supervision is required for the trunks used for
this feature.
When an entry is made in Program 15-22-01 for a Mobile Extension, ports are reserved for
Mobile Extension usage in groups of 2.
To keep consecutive port numbering for blades, you may wish to consider starting Mobile
Extensions at the upper extension port range.
When using Mobile Extension in a NetLink Network, the ISDN/PRI can be utilized in the
Secondary systems.
Calls on Mobile Extension can be easily picked up from a telephone in the SV9100 system.
This is done via a Barge-In key (34+Mobile Ext# or 34+*) * will Barge in to the Extension
that Call Forward Both Ring is set to. If no Forward Both Ring is set, the key will act as a
basic Barge-In key.
A Progress Tone is played to the caller until the call to the Mobile Extension number is set
up.
