after stripping.
DID Stripping
A number of leading digits to be stripped from the original
called number. If prefix or stripping has been given but DID
of Extension is not bynumber, the result of digit
manipulation is dialed in a DTMF string after the call has
been answered by the DID extension as an automatic 2
nd
dialing.
Language
Preferred language for system instructions heard from the
trunk.

Advanced Settings Select to see more settings shown below.
DTMF Mode
Select a preferred DTMF mode, RFC 2833 or SIP INFO, for
this trunk in the list. This must match configuration on the
server side. If the user does not know the DTMF mode on
the server side, select Not sure from the list, and SDP will
automatically detect the DTMF mode is Inband or
RFC2833.
Try Peer-to-peer RTP
Click NO to disable or 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.
Bandwidth Limitation
Leave it blank to disable or, specifies a limit of bandwidth in
kbps for call admission.
