I have an ipo with 9.0 on it and the UCM running vmpro and one-x. I have the one-x mobile preferred app on my iPhone and it is connected up. I have power user licenses selected for the user that I have selected to test this with (both of the users). I have an fqdn for the one-x and an fqdn for the IPO (different ones). My user doesn't have a real extension (no handset), but the other user I am working with does. I can call via the IPO utilizing my mobile device (having the ipo call me then the number I am dialing). When I select VOIP, everything connects up correctly and I am able to dial the other user that is using the mobile app. When I try to dial an internal extension (not on the mobile app) to the IP Office or dial an external number I see an error of "can't allocate resource" in the monitor. I have to be missing something here, but I can't seem to find what it is. Your comments and ideas or much appreciated. Thanks
