Configuring VSTG and VCG Properties |
The Vocera SIP Telephony Gateway does not have a direct physical connection to the IP PBX (or VoIP gateway). However, some IP PBXs support using the OPTIONS message to ping the PBX to determine if the SIP trunk is up. The following parameters are for sending an OPTIONS message to the IP PBX to determine if the SIP trunk is still alive or not. If the connection goes down (perhaps due to a network problem), an email notification is sent to the Vocera administrator.
Property |
Description |
---|---|
VTGUseOPTIONSForKeepAlive |
Whether to use the OPTIONS message to ping the IP PBX to determine if the SIP trunk is up. The default is TRUE. Note: You should only set this property to TRUE if your PBX supports
using an OPTIONS message as a keep-alive mechanism.
|
VTGOPTIONSKeepAliveInterval |
Specifies the time interval between pings of the IP PBX in seconds. The default is 30, but you can set it as low as 5. |
VTGOPTIONSKeepAliveToUser |
Specifies the number for the user part of the To header and for the Request URI. The default is "trunk_status". In most cases, you should not change this value. You can specify a null string (""). Do NOT change the default value to a real user number. |
VTGUseOPTIONSKeepAliveText |
Whether to include the text "keepalive" in the OPTIONS message payload. The default is TRUE, which is appropriate for most IP PBXs. Note: If you are connecting to a PBX using Dialogic Media Gateway, set
this property to FALSE.
