Yealink phones with multiple lines off 1 system

Hi there,

Just a quick question.
I have several yealink phones, 4 sip lines and 1 dahdi line on my asterisk box

I’d like to get the line buttons on the yealink to show when the lines are busy. Is this possible? I’ve had a quick look through the options and there doesn’t seem to be an immediately obvious way of doing it.
If someone could point me in the right direction I would be most grateful



You can see if other extensions are busy by subscribing to the extension hint (look at BLF on the phone).

You can use Asterisk SLA to monitor the DAHDI line (see sla.conf in your Asterisk samples for examples).
