[cisco-voip] ICT Non-Gatekeeper Controlled

[Peter Slow]

Marcio,
 Fast start (fast connect) outbound calls will always require an MTP
due to the way the ITU-T spec requires the "proposer" to support any
of the multiple advertised codecs and the way this was implemented in
CM.

Video + MTPs == Badness.

MTPs handle video using the "passthrough" codec. this is something
that i have never personally seen work properly in the field - you
want to try your best to avoid forcing MTP or transcoder allocation
along the path of a video call.

Why do you require fast start? are you having audio cut-through delay issues?

Tell us a bit more about what prompted the change. Please also include
the version of IOS on your MTP/transcoder and Unified CM. (maybe i can
find something regarding passthrough codec support)

The best thing for you in this case, is going to be to try to avoid
using fast connection procedures, since that requires MTP invocation.

-Peter
