Call Handling 66
SBX IP 320 Features & Operation Guide
4. Under the Mobile-Ext In Used State, the extension cannot receive any digits.
5. If another extension tries to call the extension of Mobile-Ext In Used State, a busy tone
sounds. Call Waiting is not supported in this case, but the user can leave a message wait
to the extension of Mobile-Ext In Used State.
Transferring a call from the mobile extension through the SBX IP 320 system:
1. Dial the transfer code (*) during the talk state in Mobile extension. The mobile extension
user hears the internal dial tone and the calling party hears the MOH.
2. Dial the extension number.
3. The call will be transferred after the mobile extension user goes on-hook state.
4. The mobile extension user can reconnect the call by pressing the code (#) in the case that
the extension does not answer.
5. Mobile Extension can transfer a call to another station's mobile extension.
To make outgoing calls from the mobile extension through the SBX IP 320 system:
1. The mobile extension user dials his DID number of the SBX IP 320 system. The internal
dial tone will sound.
2. The mobile extension can proceed to make an internal or outgoing call with CLI number
of extension.
Conditions
• If the extension is busy, forwarded, or in the DND state, calls will not be routed to the
mobile extension.
• When making an external call from a mobile extension through the SBX IP 320 system, it
sends the CLI number of the Station extension; the mobile extension cannot use the
transfer feature.
• After the no answer timer expires, a call will be routed to the DID no answer destination
(the no answer timer of the SBX IP 320 system is shorter than GSM).
• This feature applies only to ISDN DID Lines, ICM calls, and transferred calls.
• The message wait or call back feature is not supported on mobile extensions.
• When on a mobile extension conversation through the SBX IP 320, the DTMF receiver is
dedicated to the mobile extension.
• A mobile extension can transfer the call to another extension. If he tries to seize a CO line
or to dial the Hunt Group or dial another destination except an extension, an error tone
will be provided.
