Therefore, if there is a function for generation of subscriptions, then this function should also offer the callback. IMO a NOTIFY is too complicated for auto-answer. You can do it much more easier with adding a certain attribute (e.g. a header) to the INVITE. This is for example what SNOM does. Just google for it, eg: http://www.voip-info.org/wiki/index.php?page=Asterisk+cmd+page http://asterisk.snom.com/index.php/Asterisk_1.4/Intercom http://www.voip-info.org/wiki/view/Polycom+auto-answer+config
