Dial Up over IP
Posted on 2012-09-19
We have rack space in a data center and have a virtual environment configured where we host servers for our clients. We have a new client who has the need for dial up modem service for interacting with a vendor that they have. There is no way around using a modem to dial up to this vendor.
Presently, we have a VPN tunnel to our office where we have one of those COMTROL DeviceMaster RTS devices that basically allows you to use a serial device over TCP/IP. A 56k external modem plugs into the COM port on the DeviceMaster and the modem is installed on the terminal server as a normal modem that the users can access. This works fine except when we lose Internet service at our office or have some packet loss due to our less than reliable ISP we have here. The modem is currently sharing our fax line as well so there are conflicts there from time to time.
I can get a copper cross connect at the data center to Verizon for hooking up a POTS line for us but that will cost $275/mo for the cross connect plus the cost of the phone line (~$40/mo).
We have also thought about installing a Cisco router w/ CME and getting a T38 SIP trunk that's capable of data transmission but these are also up there in price and the cost of the router has to be figured in as well. We tried a magic jack and obviously it didn't work either as the quality of the dial tone isn't good enough to support the data connection.
Does anyone have any ideas on anything out there that I could get dialtone to a modem in the rack at the data center without having to pay these fees?
