CIPC & Microsoft Firewall Client

Unanswered Question

Hi,


I have a cu trying to run latest version of CIPC (same problem confirmed with previous versions as well), during testing we experienced only incoming (one-way) voice. After troubleshooting and isolating the issue it shows that once Microsoft Firewall (ISA) Client is installed, that breaks the CIPC. Just disabling FW-client service does not help.


Has anyone seen this issue, and if so, is there a solution? My knowledge of the ISA-client is very limited. :)


Best regards,

You may check with MS support why they are blocking RTP traffic.

to confirm just gather sniffer capture to confirm RTP stream arrives to the NIC

Once the F/W-client is installed, the CIPC outbound counter from call statistics does not increment at all, so no outbound RTP-stream reach the NIC at all.


I do believe MS support is the next step, but I'm still curious if anyone else has seen this issue.
