Stage Method Syntax - ch1-8:1; {all channels 1 to 8 are set to value 1 or 2}
Stage method can be set to either 1 or 2.
In simple words, if you need to make a direct PSTN call from a VOIP endpoint you
should set this to 1. When you set it to 2, you will first dial one of the VOIP channel
accounts from the VOIP endpoint, this will result in getting a PSTN line dial-tone to
then dial out the destination PSTN number.
Most implementations require this setting to be configured to 1.
Min. Delay before Defaut is 100ms.
Dial PSTN This needs to be equal or slightly higher than the Current Disconnect threshold setting,
so that once the FXO line is stable after the threshold period, the gateway can dial out.
Again, it should be touched only if there are PSTN line detection issues.
Offhook Auto This is an extremely important setting to make sure incoming PSTN calls are picked
Dial up and forwarded to the correct VOIP destination.
User ID - This parameter allows users to configure a User ID or extension number to
be automatically dialed upon FXO line off-hook.
SIP Server - You also need to specify the Profile of the user id configured above (p1
stands for Profile 1, p2 stands for Profile 2 and so on).
SIP Destination Port - Along with the user-id and Profile, you also have the option to
choose the destination port where you would like to send the call. By default it should
be set to ch1-x:5060; (x can be 4 or 8 depending on number of ports).
Caller ID Scheme The GXW410x supports 5 different types of schemes:-
Please check with your PSTN service provider (or traditional PBX specs) for which
caller ID scheme it supports.
