[cisco-voip] Best T38 Protocol Choice?

[STEVEN CASPER]

I am getting ready to do some testing with IP Trunking and T38 and I was curious as to what folks think is the best protocol choice. I will be using VG202/204 devices with CUCM 6.1.3 integrated to a CUBE. Looks like my choices are:
 
MGCP
H323
SIP
SCCP (limited to NSE?)
 
Up to this point we have been deploying VGs using MGCP and passthrough as ATA replacements and this has been working fine when used at sites with PRIs.  I am trying to think long term here so I am wondering if using SIP with T38 might be the best way to go since the IP Trunk and the associated CUBE will also be using SIP. Any thoughts would be appreciated!
