Not a 3cx issue but more so a issue where I'm seeking for advice from others on here about this topic below:
Does anyone know how to get a Fanvil GA10 to work with an elevator help button? We get a dial tone from the elevator panel to the GA10 and can call out and in just fine using a regular phone, but plugging it into the elevator panel and pressing the help button, it doesn't call out.
Elevator company claims the panel cannot see a dial tone and it's due to the DTMF setting. I went into line -> SIP -> Basic settings -> Changed DTMF Type: to all options, and none of those worked.
Anyone have experience with this and know what it could be?
