We're looking into having phones play different ringtones when called by an external number as opposed to an internal one using the alert-info header. Is there any existing functionality for this? If not, which component would be the most suited for adding this value to SIP traffic from the gateway? _______________________________________________ I think the way to do this is to add another "redirector" plugin to the Registrar. The plugin would detect the INVITEs from the gateway that do not already have an Alert-Info header and provide a contact URI which is the same as the current request-URI but with "?Alert-Info=..." appended. The plugin should specify a high "priority" value, so its mapping overrides all others. The way it functions is that the incoming INVITE to sip:xxx@domain is redirected to "sip:xxx@domain?Alert-Info=...", which when the proxy acts upon it becomes an INVITE to sip:xxx@domain with an additional Alert-Info header. This second INVITE is also sent to the Registrar, but it doesn't trigger the new plugin and is processed normally. It's probably not something you want to tackle unless you've got a reasonably good handle on how sipXecs processes SIP and don't mind C++ coding.
