I am trying to get a distinctive ring from an extension and I found this How To
http://www.freepbx.org/support/documentation/howtos/how-to-enable-distinctive-ringing-alert-info-for-calls-from-particular-
My system is Freepbx 2.10/ and I am using AAstra phones. I am testing in my office and want to deploy this using an ATA with door boxes to autodial to a group of phones and alert the phones with the distinctive ring. I tried using the Alert_Info on a group in my office but it didn't apply to internal calls, only external DID calls. I am using the OSS phone configurator at the moment to proof the concept.
The problem is that it doesn't seem to work consistantly. I have an aastra 6731i and a 6757i. If I call internal direct dial from the 57 to the 31 the distinctive ring doesn't work, but the other way around does. The CFG file is the same and both phones are set the same in the web gui.
What am I missing? Suggestions?
Thanks
