VPN users using IP Communicator - One-way audio

[aelsbernd]

No config changes that I am aware of, it just suddenly stopped working.

I am able to ping VPN user and VPN user is able to ping back... from voice vlan as well.

VPN users are able to hear other VPN users using IP Communicator.

When I call from LAN, VPN user can hear me but I cannot hear them.

Any ideas?

Resolved, issue was unrelated to Cisco equipment.
