Grandstream Networks GXW-410xv Manuel D’Utilisation

The minimum session expiration (in seconds).  The default value is 90 seconds.  

If selecting “Yes” the phone will use session timer when it makes outbound calls if 
remote party supports session timer. 

If selecting “Yes” the phone will use session timer when it receives inbound calls 
with session timer request.  

If selecting “Yes” the phone will use session timer even if the remote party does not 
support this feature. Selecting “No” will allow the phone to enable session timer only 
when the remote party support this feature.  To turn off Session Timer, select “No” 
for Caller Request Timer, Callee Request Timer, and Force Timer. 

As a Caller, select UAC to use the phone as the refresher, or UAS to use the Callee 
or proxy server as the refresher.  

As a Callee, select UAC to use caller or proxy server as the refresher, or UAS to 
use the phone as the refresher. 

Session Timer can be refreshed using INVITE method or UPDATE method. Select 
“Yes” to use INVITE method to refresh the session timer.  

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 
inter-networking is to be supported. A user’s request 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. 

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. 

The GXW-410xv supports up to 5 different Vocoder types including G.711 A-/U-law, 
GSM, G.723.1, G.729A/B.  The user can configure Vocoders in a preference list 
that will be included with the same preference order in SDP message. The first 
Vocoder in this list can be entered by choosing the appropriate option in “Choice 1”. 
Similarly, the last Vocoder in this list can be entered by choosing the appropriate 
option in “Choice 8”.  

Default is Standard. Choose the selection to meet some special requirements from 
Soft Switch vendors like Nortel, Broadsoft, etc.
