[cisco-voip] IP Communicator 7.0(1)

[Cauthen, John A.]

We are experiencing a one-way audio issue when using IP Communicator
7.0(1) through VPN.  The caller can hear the other party but, the other
party cannot hear the caller.  Troubleshooting:

 

-          CIPC works in the office on the LAN

-          CIPC works when directly connected to a port on the core
Switch on the VPN VLAN (receiving a VPN IP address)

-          CIPC doesn't work through the Cisco ASA SSL VPN solution, or
the Cisco VPN Concentrator 

-          We have also used Wireshark to see if there was any
difference in the communication when going through VPN compared to when
CIPC works.  The only thing I notice is that when connected to the VPN
the communication is one-way as well.  The source is always the voice
VLAN.

 

We are on CUCM 6.1(2) using SCCP.   If you can help please let me know
what I am missing...I am sure it is just staring me in the face.

 

 Thanks,

 

John
