[Freeswitch-users] Alert-Info header not understood by SPA phones

Hi List, I am trying to setup a custom ringtone for internal calls for cisco SPA504G through the Alert-Info header. I have put <action application="export" data="alert_info=Office"/> before the bridge as stated on the wiki but the sip header does not seems to be recognized by the phone. The invite the alert-info header is sent correctly in the sip invite but it contains extra brackets (Alert-Info: <Office>) wich confuses the phone as it is expecting "Alert-Info: Office". I have also tried <action application="set" data="sip_h_Alert-Info=Office"/> but it does not make any difference. Is there any way to remove these brackets ? Thanks you! -- Best Regards, - vma.
