I have been abandoned by a provider from Michagan who sold me a elastix pbx box with promised to provide phone number and helped get the phones to work. i have paid for the phone numbers and the services that does not work. somehow he could not get the phone incoming/outgoing calls to answer. he quickly told me the distance is the problem or some sort of code g27 is the problem, that he will get back with me or find someone locally here in Aurora Colorado to help so far no respond from him. secondly we have no phone service for a month now. i have put some much money into this just don't know what to do. i could dispute the charges through paypal and my bank for a service that does not work. any suggestions on how to get the phone working. i must admit that i don't know much about this system of pbx.
