will only work if the other party is also
supporting fast start. This feature in H.323
is optional, meaning it can be ignored by
an endpoint not supporting this feature,
hence making the snom phone revert to
the normal H.245 signalling on a separate
channel. Note that if Fast Start is being
used, Out of band DTMF might not work
because the DTMF info is relayed on the
H.245 channel.
user_h323_h245_tunneling1
V
alid values: <true>, <false>
Default: false
Description: H.245 Tunnelling option
sends tunnelled H.245 messages within
an H.225 pdu. This also accelerates
connection setup if both parties are
supporting
this feature.
trace
Valid v
alues: <true>, <false>
Default: true
Description: Enable tracing output of the
current protocol s
tack.
user_h323_h4501
Valid val
ues: <true>, <false>
Default: false
Description: If flag is set to <true>,
H.450 supplementary services are used,
otherwise (<fals
e>) it is facility-based.
Gateway prefixes (H.323 only)
user_external_line_prefix1
V
alid values: e.g. <0>, <111>
Default: blank
Description: Prefix used for reaching
outside numbers via an H323 gateway.
This prefix will be replaced by the
gateway_prefix in a dialled number for
calling outside numbers (see gateway_
prefix).
user_gateway_prefix1
V
alid values: e.g. <*5>
Default: blank
Description: Prefix with which an ISDN
gateway is registered at the gatekeeper.
The phone will replace this prefix with the
external_line_prefix in a dialled number if
it is starting with the external_line_prefix
(see external_line_prefix).
Hence the user doesn’t have to dial
numbers like 5*1234567 but can instead
dial 01234
567 with the same effect.
