When using IP Comm 22.214.171.124 through a CP SecuRemote VPN Client connection, we are a) unable to hear the VM greeting or leave VM when calling an internal ext; b)retrieve VM; c)no audio in either direction when two users connect via VPN using IP Comm; d)register w/CM over wireless through VPN.
We are able to make "in network" (4-digit dial) calls and make external calls normally with IP Communicator through the VPN client. VM can be left to an external number (cell, other) fine but not to our Cisco IP Phones. We also use Unified Messaging.
The call manager version is 4.1.(3)
- The OS version is 4.4.8.sr7
CheckPoint NGX Firewall / Nokia IPSO R60_HFA_05. We are not issuing DHCP addresses to VPN clients when connected. No drops are seen in the FW logs.
