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

[Vallimamod ABDULLAH]

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!
