Can Push-To-Talk be held down? Continous duplex conversation.

[marked99]

Can the Office Intercom's talk button be toggled on and off instead of pushed momentarily? This would allow you to talk without holding the PTT button down continuously.

 

Also, can multiple users hold their talk buttons down at the same time so that their conversation is full duplex. i.e. two people can talk at the same time and both will be heard.

 

Basically can the office intercom work in the same way a phone does, that is full duplex?

 

Thanks for your assistance,
