Enable 100rel The use of the PRACK (Provisional Acknowledgment) method enables reli-
ability to be offered to SIP provisional responses (1xx series). This is very im-
portant if PSTN internetworking is to be supported. A user’s wish to use reli-
able 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 mes-
sage will be set to anonymous, essentially blocking the Caller ID from display-
ing.
Auto Answer When set to “Yes”, GXV-3000 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. Default is No.

/U-law (nickname as PCMU/PCMA), GSM, G.723.1, G.729A/B.
