Good Day list, I have read wiki pages I have googled to death and am getting no closer to understanding the methodology of onhold music. Maybe I am trying to do something that is just not possible: Here is my desire. 1) Call comes in to the asterisk box via Zap channel 2) call is answered by SIP/100 3) call is parked 1) Sip/200 unparks the call and places the caller on hold (by pressing hold button on the SIP Phone) I would like to have any callers that have been placed on hold from this extension to hear musicclass "SALES" Repeat steps 1-3 above 1) Sip/300 unparks the call and places the caller on hold (by pressing hold button on the SIP Phone) I would like to have any callers that have been placed on hold from this extension to hear musicclass "SUPPORT" I have found discrepancy in the source code between using musicclass and musiconhold therefore I have tried both of them individually and simultaneously. PS> I know the different classes of music are working because I can specify them to be used in the queues I have set up. Bottom line is "Can I specify the music class that a caller hears based upon WHO puts them on hold?: Thanks for your assistance Musiconhold.conf ; ; Music on hold class definitions ; [classes] default => quietmp3:/var/lib/asterisk/mohmp3 general => quietmp3:/var/lib/asterisk/mohmp3/general Support => quietmp3:/var/lib/asterisk/mohmp3/Support Sales => quietmp3:/var/lib/asterisk/mohmp3/Sales Sip.conf [general] port = 5060 ; Port to bind to (SIP is 5060) bindaddr = 0.0.0.0 ; Address to bind to (all addresses on machine) disallow=all allow=ulaw allow=alaw context = from-sip-external ; Send unknown SIP callers to this context callerid = Unknown musicclass=general [200] . . . musiconhold=Sales musicclass=Sales [300] . . musiconhold=Support musicclass=Support -------------- next part -------------- A non-text attachment was scrubbed...
