Thanks for the input Jim.1- Can you please shed some more light on why use ASEQ
and what you mean by glare?2- Also what is virtual group option?RJ45 is used
for Sangoma. And seen a note somewhere that using Asterisk can't send CLID/Name
with NI-1 so it's definitly NI-2 to go with as you said.Thanks again,Bruce
