CIPC 7.0.4 to CUCM 7.1.5 via CVPN 5.0 registers with CUCM Server IP

IP Communicator 7.0.4 connecting to CUCM 7.1.5 via CVPN 5.0 over a verizon wireless card is the environment. 

One way audio is the result.  The reason is obvious: CUCM 7 shows the IP Address of the CIPC client as the same IP address of the server causing my RTP stream to be sent to the wrong place. 

This is true regardless of device settings and whether I specify a SEPXXXXXXXXXXXX, doesn't matter what the TFTP servers are set to.  if I set TFTP1 as then the client IP Address shows up as regsitered to with an IP addres of etc...

IF HOWEVER we login to the x86 windows 7 pro machine with the administrator account, then the CUCM 7 server shows the IP Communicator regsitered with the correct IP address that was issued by the ASA VPN and 2 way audio works.  so we make those settings, save them, and restart the machine logging in again as the user.  everything goes back behaviourly as it was before.  This is in spite of the fact that the settings are different.  so for example the tftp1 server is and server2 is it doesn't matter the CIPC client reaches out to like it was cached somewhere in the user hive.

anyone got a fix or am I headed for TAC?

thanks in advance,

Re: CIPC 7.0.4 to CUCM 7.1.5 via CVPN 5.0 registers with CUCM Se

Did you ever find a solution for this?  I am having the exact same problem, and your post is the first I have found that confirmed other people have seen the issue....

FWIW, I have seen this issue in 7.0.4 and 7.0.5.

Thanks in advance,
