asterisk users - Jan 2010 - SIP over VPN -- no audio to other remote/VPN connected phones

Hello,

I am having a problem with my current SIP over VPN setup.

We have a server running asterisk at our office.  All the phones in the 
office are on the same network / local to this server.  We also have two 
employees with home offices using SIP phones over VPN to connect to the 
asterisk server.  These phones have no problem with calls to the phones 
in the office, however there is no audio when trying to place a call 
from one remote phone to the other.

I'm assuming this is a routing issue, but I have no been able to come up 
with a solution.

Thanks for any advice.

One thought: if you are using "reinvite" try turning that off. That
will be
a clue.

It would seem that both phones are on the local net via VPN, and should be
able to talk to each other if they can talk to anyone in the office. (As you
know.) So look for clues as to real paths to each other.

We have that solution running fine...

Is your VPN termination a Linux box?  Is it also the office router?  Is it
also the firewall?

The VPN termination is a Cisco/Linksys RV042.
