Session Timer can be refreshed using INVITE method or UPDATE method.
Select "Yes" to use INVITE method to refresh the session timer.
PRACK (Provisional Acknowledgment) method enables reliability to SIP
provisional responses (1xx series). This is required to support PSTN inter–
networking..
There are 4 uniquely defined ring tones:
•
One (1) System Ring Tone: when selected, all calls
ring tone.
•
Three (3) Customer Ring Tones: when selected, incoming calls from
designated account will play selected ring tone.
If this parameter is set to "Yes", the "From" header in outgoing INVITE message
will be set to anonymous, essentially blocking the Caller ID from displaying.
Default is No. If set to "Yes", GXP–2000 will automatically switch on speaker to
answer the incoming call. Set to Intercom/Paging mode, it will answer the call
based on the SIP info header from the server.
The GXP–2000 supports up to 5 different Vocoder types including G.711(a/µ)
(also known as PCMU/PCMA), GSM, G.723.1, G.729A/B.
Configure Vocoders in a preference list that is included with the same preference
order in SDP message. Enter the first Vocoder in this list by choosing the
appropriate option in "Choice 1". Similarly, enter the last Vocoder in this list by
choosing the appropriate option in "Choice 8".
Jitter Buffer Delay is pre–configured and can not be changed.
Default is Standard. Choose the selection to meet special requirements from Soft
Switch vendors.
