The Mediant 1000 gateway supports the following supplementary services:
 Call Hold and Retrieve; refer to Section 8.1.1 on page 257
 Consultation / Alternate; refer to Section 8.1.2 on page 257
 Call Transfer (H.450.2); refer to Section 8.1.3 on page 258

To activate supplementary services on the gateways you should Enable Hold, Transfer,
Forward, MWI, name identification, and Call Waiting services either from Web browser or
in ini file. To use these features all participated, in a call, H.323 endpoints should comply
with the H.450 standards.
Note: When working with application servers (such as BroadSoft’s BroadWorks)
in client server mode (the application server controls all supplementary
services and keypad features by itself), the gateway’s supplementary
services must be disabled.
8.1.1 Call Hold and Retrieve
 Active calls can be put on-hold by pressing the phone's hook-flash button.
 The party that initiates the hold is called the holding party; the other party is called the
held party.
 After a successful hold, the held party should hear Held Tone and the holding party
should hear Dial Tone.
 A retrieve can be performed only by the holding party while the call is held and active.
 The holding party performs the retrieve by pressing the hook-flash.
 After a successful retrieve the voice should be connected again
8.1.2 Consultation / Alternate
 The Consultation feature is relevant only for the holding party (applicable only to the
Mediant 1000/FXS module).
 After holding a call (by pressing hook-flash), the holding party hears dial tone and can
now initiate a new call, which is called a consultation call.
 While hearing a dial tone or when dialing to the new destination (before dialing is
complete) the user can retrieve the held call by pressing hook-flash.
 The held call can’t be retrieved while Ringback tone is heard.
 After the consultation call is connected, the user can switch between the held and
active call by pressing hook-flash.
