We have a Telstra Gateway TG799

[CAS06]

The original handset has died - I have purchased on recommendation from Telstra shop, a T-Voice 503 but I can't get it to register - solutions please

Have you pressed the DECT button for 5 seconds before trying to register the phone?

[CAS06]

Thanks, yes and that does nothing. Will no doubt have to ring Telstra and wait in line for an eon.

Have you tried factory resetting the gateway?

[CAS06]

How do I do that?

[cf4 · Accepted solution]

To reset gateway press reset button for 7 seconds while gateway is powered on. See link below for location of button.
