Messenger Revisited


In an effort to simplfiy the installation and administration of the Messenger service, CRT has rebuilt it from the ground up. First let’s review how Messenger works. The service translates text into a speech message, makes a phone call, and then plays the message. We refer to this process as event based phone messaging. The text can come from different sources. In it’s current version Messenger is able to grab text from an email or a web form. 

The earlier version of Messenger functioned in a similar fashion but had additional capabilities which added complexity to the installation and administation processes. Since these additional capabilites had little to do with the core function (event based phone messaging) of the Messenger service they were removed from the current version.

The Messenger Project page has been updated with additional information about the new version. Look for the the official Messenger release this week.

[8/4/06 Messenger released. Messenger 1.0 is now available for download at the new Messenger Project page.]

    If you don’t already have it planned, it is worth mentioning that this project can be implemented without any special hardware if you use IAX trunking ( Junction networks ( is one vendor that implements this at a reasonable cost. IAX trunking also solves some problems with detecting if the line has been answered, this can be difficult when using a POTS line and the Digium cards. Something else to check out is Cepstral’s ( line of voices. They are very affordable high quality voices that can be used to customize your text to speech messages.

    Yes we have looked into connecting to an ITSP via IAX. This will be a feature available in future versions. Thanks for the links, they will be helpful to people who would like to move ahead and try it themselves. For POTS connections digium cards are available at Ebay from $14.00.
