Not all Cisco phones support mediaStream #2
Description
The Cisco model CP-6921 does not support the newer startMedia and stopMedia API. It DOES support the older RTP streaming API that uses the ExecuteItem's with RTPRx: or RTPMRx: URIs. When this program is used to send to one of these phones it issues an error message "index was outside of the bounds of the array" instead of saying the phone does not support the startMedia API
This was verified through work on an issue with a similar Github project the usecallmanagernz mediastream command that is part of it's commands set. That work can be read about here:
It is also likely that older model Cisco phones such as the 7940 also do not support the newer startMedia API.
So far all newer models of Cisco phones (the x8xx model series) running enterprise firmware that I have tested also support the older RTP streaming API.
This probably should be mentioned in the documentation for this software
