Change the intercom alert tone length

[haukri]

Hi, I have a problem using the intercom feature. I have a couple of Yealink phones and we use the intercom feature a lot.
The problem I am having is that the phones only beep for a split second before automatically answering the intercom call.
I have isolated the problem down to the SIP INVITE sent by 3CX to the phone.
The INVITE messages includes:

Request-URI: <sip:EXTENSION@IP>;intercom=true
Call-Info: <sip:3cx.pbx>;answer-after=0

The problem is that 3CX is sending answer-after=0 which the phones understand as an immediate answer. I would like to change it from 0 seconds to 1 or 2 seconds.
Does anybody know if this is somehow possible?

Best regards,
Haukur

Nope you can't. This could be adjustable on the phone-side tho.
