We have tested voice functionallity in Spark with two different server installations and with multiple clients. It would appear that the Jingle protocol is not well supported anymore and that voice functionality has limited support and functionality.
I have seen many posts that state issues with this protocol. We have disabled firewalls on two computers on the same physical switch and can see the traffic with a protocol sniffer but the data sent does not appear to be recieved in a sufficent manner to establish a call. I am not sure how to proceed at this point. Is there a article I may have missed.
Any assistance would be greatly appriciated.
