Take a look at the IDatatel products (
http://ipdatatel.com/products/). They work with DSC and Honeywell panels as well as a bunch of others. The basic model is via internet, but they also have an Internet+Cellular version. For monitoring, you might try AlarmRelay (
http://alarmrelay.com). Good price and they offer a remote access portal as well. Note the IpDatatel products are not accessible from Indigo (I.e. no API) so you would still need some other means of accessing the panel for Indigo use. For Honeywell/Ademco/Vista panels you can use AlarmDecoder's ad2* products (
http://www.alarmdecoder.com/catalog/index.php). They also work on DSC panels but the AD2USB plugin has never been tested with that configuration.
