[cisco-voip] Cisco IP Communicator Issue

[Andy Infante]

If you find an answer to this, we've had this same problem for quite some time.  It happens such that any user on VPN calling another user or vice versa will have to dial twice to get the call to be duplex.

Subject: [cisco-voip] Cisco IP Communicator Issue

We have a Cisco CME/CUE setup in our office and I'm trying to work on a solution for those people who are on the road, but still need access to their local office phone.

I installed the Cisco IP Communicator and used the corporate VPN to allow connections back to our office.  On the CME, I created a new ephone and associated with the same ephone-dn that the user's physical phone resides on.

I tested the following scenarios using the IP Communicator:

1.       Placed a call from an external phone (like a cell phone) to the DN.  The phone rang & the  call was connected normally.

2.       Placed a call to an external phone from the IP Communicator.  The call was connected normally.

3.       Placed a call to another number internal to the CME.  Incoming audio (recipient could be heard), but outgoing audio (me speaking) did not work.

Is there a reason why I have problems with bullet #3?  The only thing I could think of is the fact that the actual physical Cisco phones are on their own private network, separate from the corporate network.  But even then, I could make/receive calls from outside phones.
