It not a firewall issue, tried adding AnyConnect to firewall exceptions in XP with no luck.

AnyConnect version 3.0.3050

IP Communicator version 7.0.4.0

O/S is Windows XP

IPC works fine with other VPN clients, also works when directly connected to network.  Issue seems to be with AnyConnect but have no idea what to check.

Hi,

Please also review the document < How Cisco IP Communicator Obtains an Audio IP Address with a VPN>:

http://www.cisco.com/en/US/partner/docs/voice_ip_comm/cipc/7_0/english/administration/guide/cag70cfg.html#wp1045281

Also you can change the settings from "Detect Automatically" to "Use this adapter(VPN) 's IP Address" to work around this.
