Its is possible for OpManager to work with a 3rd party SMS gateway provider such as  http://www.textanywhere.net/?

For our internally developed systems, we use  http://www.textanywhere.net/ and messages are sent to as SOAP webservice requests.

Or is there a tutorial on getting OpManager (running on vSphere) to work with a GSM phone, I'm confused how the Device is shared with the VM.
