configured on the device side as well.
Pickup Group The usergroup that the extension can pick up. The
extension can set a usergroup that when any extension in
the usergroup rings, the extension can press *8 to pick up
the call in ringing state.
Select Include Reachables check box to be able to pickup
calls that belong to other usergroups which is configured in
Reachable User Groups of the selected usergroup.
Language Preferred language for system instructions heard from the
extension.
Voicemail Select enable to allocate voicemail account for the
extension.
Voicemail PIN PIN to access voicemails. This is mandatory if above
voicemail option is enabled.
Max Voicemail Space Enter maximum space in KBytes for voicemail. Enter 0 or
leave it as blank for not limiting the voicemail space. The

voicemail will be recorded until the storage is full.
Disable Fast Bridging Select to disable express media forwarding.
)With Fast Bridging feature enabled, if the two parties
involved in a call (for example, one IP extension and
one SIP trunk) use different DTMF modes
(RFC2833/SIP INFO/Inband), inline transfer (*#) or
2nd-dialing might fail. To avoid such problem, it is
recommended to set the same DTMF mode for all IP
extensions and SIP trunks in the IPBX, as well as for
all IP phones registered to the IPBX. If it is not
feasible to set the same DTMF mode for some IP
extensions or SIP trunks, and inline transfer or
2nd-dialing is necessary for those IP extensions or
SIP trunks, the Fast Bridging feature can be disabled
on a per IP extension and per SIP trunk basis. Note
that Fast Bridging is enabled by default.
Try Peer-to-peer RTP If click YES, IP PBX will attempt to notify the two peers in a
conversation to try peer-to-peer RTP transmission. This is
suggested as long as phones support INVITE or UPDATE
method during a connected call to save the resource of IP
PBX. However, only SIP INFO DTMF mode phones should
enable this since other DTMF modes require IP PBX being
RTP relay server to support in-line transfer.
DTMF Mode Choose preferred DTMF mode for this extension. Currently
supported types include RFC2833, SIP INFO, and in-band
tone. It must match configuration on the device side.
)In-band DTMF mode consumes the limited DSP
resource when using a highly compressed codec,
such as G.729 or G.723.1. Therefore, calls will not
connect with such setting if DSP is not installed.
Although using a low-complexity codec such as G.711
does not require DSP, DTMF detection still takes
considerable CPU resource and impacts several
system specs. Be cautious when configuring an
extension with in-band DTMF mode.
