Mitel MX-ONE VAD/CNG/Silence Suppression

To determine if "Silence Suppression" is activated:

~>sip_route -print -profile Default | grep MediaSendCN
MediaSendCN: yes

Surprised to see it is set to yes? So was I. Documentation regarding the MGU pointedly states that VAD/CNG (Voice Activity Detection / Comfort Noise Generation) negatively impacts voice quality, but does improve DSP resource usage.


To fix:
1. Edit the appropriate profile to "no"
2. Restart SIPLP
3. sip_route -print -profile Default | grep MediaSendCN

An alternative is to edit VARC parameter D7, but the recommendation is editing the sip trunk profile.
