Guys,
H.323/8.1.7.2 says :
After establishment of a call using the Fast Connect procedure, either endpoint may determine that it is necessary to invoke call features that require the use of H.245 procedures. Either endpoint may initiate the use of H.245 procedures at any point during the call, using tunnelling as described in 8.2.1 (if h245Tunnelling remains enabled) or a separate H.245 connection. The process for switching to a separate H.245 connection is described in 8.2.3.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
8.2.3 says:
When H.245 encapsulation or Fast Connect is being used, either endpoint may choose to switch to using the separate H.245 connection at any time.
There seem to be some contradiction in there: is it "after establishment" or "at any time"?
Do you have to wait for after CONNECT to establish a separate H.245 channel or not?
The case I'm interested in would be to send SETUP with fastStart, then receive ALERTING with fastStart. Then can either end initiate H.245 before CONNECT? If so, what if third party pause and redirection is initiated before CONNECT?
