[cisco-voip] Cisco IP Communicator Issue

That gives me a good place to start.  Since you guys think it’s a routing issue, do you think it’s because my IP phones are on an isolated network?  You can’t even ping the IP range that the phones use unless you’re on the CME router itself.

I agree with those suggesting routing issues.  Sounds like the default gateway for your internal IP phones may be sending the the return rtp traffic back a different route.

	most of the times one way audio issues are related to routing problems than an issue with the CME, CCM or the phone.
	and its more common to have a one way audio issue when a vpn tunnel is involved. could you please check your routing table.
	what i'd check is the routing table or whatever you have on the vpn. it looks like the traffic coming from your office to your ipc is getting lost somewhere that's why they can hear you but you can't hear them

	make sure that your VPN knows about the phone subnet so that rtp knows how to get to the office phone.

		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.
