I have tried several modems and none seem to work with the Geovision hotline alert function. The closest that I have gotten is that the modem dials out, but it will not play the wav file message that I recorded when I answer the phone.
Geovision will not give out exact an exact model number and manufacturer that is certified to work. I have already tried contacting them. They deter users from using this feature, but we have a client that really needs this to work.
Any help would be greatly appreciated. If someone has a working modem, please reply with exact make and model #.
Sincerely.
