Description:	I'm using the alert-info sip header to use distictive ringtone on Polycom phone. Basically, the polycom need to see a specific value in the alert-info field. In Asterisk 1.2, I was using : Set(_ALERT_INFO=info=Custom 1) to set the ringtone and to overwrite it later, it was using the same thing with another value : Set(_ALERT_INFO=info=Custom 2) In Asterisk 1.4, now I'm using : Sipaddheader(Alert-Info:Custom 1) but if I try to overwrite it later with Sipaddheader(Alert-Info:Custom 2) it won't work, it add a second header instead. The polycom will now use the latest SIP Alert-Info header instead of the newest. ****** ADDITIONAL INFORMATION ****** I will include the wireshark debug as soon as possible.
Comments:	By: Olle Johansson (oej) 2008-05-16 08:45:19 Run dumpchan() on the channel after you've added the first header, then change the channel variable that contains your header. By: Olle Johansson (oej) 2008-05-16 08:45:59 sipaddheader does not check for duplicates, since you're allowed to have multiple headers with the same name. By: Leif Madsen (lmadsen) 2008-05-16 10:17:27 How hard would it be to add an 'r' option for 'replace'? I know this is a feature request, so feel free to ignore my idea :) By: dimitripietro (dimitripietro) 2008-05-16 10:22:45 It's working fine, should it be added to the documentation ? By: Olle Johansson (oej) 2008-05-16 10:26:59 File feature requests on http://www.asteriskideas.org - thank you! Good to know that it's working. Documentation updates are always welcome!
