Unity Connection access via Communicator cuts off

[AskQ2Forum_2]

           we have unity connection 8.6  users that are accessing it via Communicator version 8 - specifically when they are leaving  a message for another user on the same server they start recording their message but then get cut off after 2 -3 seconds (gets prompt to send this message press #). No problems when they are leaving a message via a mobile or via an ip deskphone - its just happening with softphones.   I tried increasing training silence setting from 3000 to 5000 but this made no difference ? anyone seen this before. calls are not specifically  going via gateways.  any specific traces that may help us with this ?

Is the issue happening with CIPC's registered across the WAN , is VPN in the picture?

Does the issue also happen if you use a CIPC that is on the same network as the Unity Connection server?

Try installing a CIPC on a PC that is connected on the same switch on which UC server is installed and check if the issue can be replicated. If yes, then we could rule out network issues and collect traces from UC and CUCM to check further.

Hi Manish,

thanks for the reply, looks like it maybe a one way firewal issue for RTP - ran a trace on connection and did not see rtp from client to Unity - so maybe only one way rtp. Just waiting for network guys to confirm one way or the other (no pun intended)

Sure, Please keep us posted.
