heard from the trunk.

Usergroup

of privilege When disabled DID, select a usergroup whose

reachability to other usergroups and trunks

will be used as the privilege of inbound calls

from this trunk.

F There may not be appropriate usergroups

to select initially. One can come back later

once the expected usergroup has been added.

DTMF Mode Choose preferred DTMF mode for this trunk.

Currently supported types include RFC2833,

SIP INFO, and in-band tone. It must match

configuration on the server side.

Try peer-to-peer RTP If checked, 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 phone and ITSP side support INVITE or

UPDATE method during a connected call to

save the resource of IP PBX. However, only

SIP INFO DTMF mode should enable this

since other DTMF modes require IP PBX

being RTP relay server to support in-line

transfer.

Bandwidth sensitive Indicate the trunk is over a bandwidth-

sensitive link, e.g. across Internet. If checked,

a limit must be specified for call admission.

3.14 PSTN Trunk Configuration

A PSTN trunk group is a logical group of one or more PSTN subscriber lines connecting to FXO

ports on IP PBX.

The PSTN Trunk Management page allows the administrator to configure PSTN trunks. By

selecting Trunk -> PSTN Trunk, one can add, edit, and delete PSTN trunks. IP PBX service

must be reloaded to activate changes.
