How does a global corporation switch to IP Voice?

Hi Dave,

Can you clarify something for me...."The Mitel systems were hooked together using Mitel's proprietary protocols, mainly because Mitel SIP trunk licences cost the thick end of £50 per channel and we would need several dozen channels, while Mitel-proprietary voice over IP (VoIP) trunks cost nothing."

When you say "..per channel.." do you mean: 1) SIP Session, 2) PRI Channel (1 of 23/24) or 3) a complete trunk (24 / 32 channels)?

Actually SIP Connect 1.1 is becoming a globally accepted standard - with liaison work in IETF and SIP Forum. Recently BITKOM (Germany) endorsed this standard. Yes, ISPs still require compliance testing to their own requirements as well, but as this matures there will be much closer alignment to the standard - same road National ISDN traveled back in the 80's. It eventually becomes a cost issue. SIP Connect 2.0 standards are now being developed addressing additional media inter-working concerns.
