How to get TA-908e to respond to OPTIONS request

[sharpy]

Hello,

We have a TA-908e successfully registered to a Genband SBC.

The Genband sends an OPTIONS packet as a Qualify (keep-alive).

We need the TA to respond with a 200/OK. Right now it is not responding with anything.

Is there a configuration we could perform to make it respond?

Thanks

On the voice trunk connected to the Genband, configure:

sip-keep-alive options

You can also set a value in seconds that the Adtran will use to poll the other side.

sip-keep-alive options 60

will poll the other side every minute.

Unfortunately this answer did not work. What it does is SEND Options keep-alives. It does not respond to the unsolicited RECEIVED Options keep-alives from the SBC.
