Can I use the call_id with action URI commands?

[nSolvePaul]

Can I do something like this:

key=Answer&call_id=xxxx

to give me better call control - otherwise I'm just guessing what is going to be happening.

Hello Paul,

For this function, it describes on Yealink administrator guide, the format is that IP/servlet?key=ASW:$call_id(like 1234)
And some other behaviors also support add call_id at the end, for example HOLD/UNHOLD.
For more detail, you can refer to the admin guide which can get from Yealink official website.

Best Regards,
Simons
