Voicemail and Auto-attendant are on the same port. Voicemails are inaccurate.
If the voicemail and auto-attendant ports are the same RUBY cannot distinguish between the two.
RUBY requires a unique device per group, it cannot share a common device between groups.
We suggest that the voicemail ports on the Ruby configuration be removed and we recommend that
if there is only a single card with ports shared between voicemail and auto-attendant that
this functionality not be used in RUBY as the PABX does not meet the requirements for it.
