frequent refreshes of registration but also cause additional network traffic. Very high values
result in large intervals of disconnection from the Gatekeeper before getting back online if
the gatekeeper reboots without sending any un-registration request to the phone.
early_start
Valid values: <true>, <false>
Default: true
Description: The early start option allows the H.245 channel to be set up earlier, and
hence speeds up the call setup. When early start is turned on, the H.245 channel address
is also supplied in the Setup message. This speeds up the call because the H.245 channel
negotiations can proceed in parallel to H.225.
fast_start
Valid values: <true>, <false>
Default: false
Description: Fast start sends encoded OpenLogicalChannel messages within the Setup
messages and hence eliminates the need for a separate H.245 channel for Codec capability
negotiation. This 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 signaling 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.
h323_h245_tunneling
Valid values: <true>, <false>
Default: false
Description: H.245 Tunneling option sends tunneled H.245 messages within an H.225 pdu.
This also accelerates connection setup if both parties are supporting this feature.
trace
Valid values: <true>, <false>
Default: true
Description: Enable tracing output of the current protocol stack.
h323_h450
Valid values: <true>, <false>
Default: false
Description: If flag is set to <true>, H.450 supplementary services are used, otherwise
(<false>) it is facility-based.
Gateway prefixes (H.323 only)
external_line_prefix
Valid values: e.g. <0>, <111>
