Re: [cisco-voip] CUCM trunk connection

In a nutshell,

1. ICT trunk = need to keep features on like Extension mobility between
clusters (this is one of 100's feature)
2. SIP trunk = if you just need a call between cluster users but don't want
funky features to maintain (see above#1)
c. H323 trunk = same as sip trunk. however this is prefered method over SIP.
