Has anyone seen the following issue?
I have 7941's and 61's with SCCP41.8-3-1S load.
We had an MOH and Annunciator issue through a firewall. It was suggested to try the Duplex Streaming Enabled CallManager service parameter.
By default it is set to False, we set it to true and tested.
Now if I call from phone a to phone b and press hold on phone a. Phone b will start to play the music on hold.
Phone B also now has no contact with callmanager. It is unresponsive, it wont end the call, transfer etc.
It is easily reproducible in different environments. i.e. doesnt look like network, looks more like phone load / behaviour.
We did an ethereal trace and you can see the phone send a Skinny Alarm to the callmanager in response to a StartMediaTransmission message.
Anyway, just thought I would ask, as I cant find any bugs in relation to it so far.
