Configuration guide for X-Lite ver. 3.0
From Zenitel Wiki
M-key and Door Opening feature from X-Lite
In order to make the buttons *, # (M-key operation) and 6 (door opening) to work from the X-Lite during conversation, the X-Lite must be enabled for SIP INFO messages.
AlphaCom use SIP INFO type signaling during connection. The X-Lite has DTMF support for SIP INFO messages, in addition to RFC 2833 and inband DTMF. But in order to use SIP INFO you need to disable the other two options.
Follow these steps on the X-Lite:
- Dial ***7469 (send)
- Once you get the advanced options menu up, filter first for DTMF. Find the Force Inband DTMF entry, double click and change the value to 0.
- Then filter for 2833. Find the RTP 2833 enabled line, double click and change this value to 0.
- Setting both to 0 will result in your sending SIP INFO DTMF.
