Telephone Features: Mobile Call Control
9.3.1 Mobile Direct Access (MDA)
For a Mobile Call Control or one-X Mobile client user, FNE32 immediately redials on switch the DDI digits received with
the call rather than returning dial tone and waiting for DTMF digits as with FNE31. This is called Mobile Direct Access
(MDA).
MDA requires the user's external telephony provider to provide a direct trunk with DDI to the system (ie. an ISDN or SIP
trunk). By assigning a specific incoming line group ID to the trunk, an incoming call route can be created for the same
line group ID with blanks incoming number and incoming CLI fields. The destination is a short code set to FNE32.
User validation is performed using the CLI in the same way as for normal Mobile Call Control. In addition the call will be
rejected no DDI digits are provided. Once connected the user can use the other Mobile Call Control features such as **.
