Enable 100rel
The use of the PRACK (Provisional Acknowledgment) method enables
reliability to be offered to SIP provisional responses (1xx series). This is very
important if PSTN internetworking is to be supported. A user’s wish to use
reliable provisional responses is invoked by the 100rel tag which is appended
to the value of the required header of initial signalling messages.
Account Ring Tone
There are 4 different ring tone that are defined:
• System Ring Tone: when selected, all calls will ring with system ring
tone.
• Customer Ring Tone 1 to 3: when selected, GXV-3000 will ONLY
play this ring tone for all the incoming calls for this account.
Send Anonymous
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.
Auto Answer
When set to “Yes”, GXV-3000 will automatically switch to speaker when
there is an incoming call.
