Hi Everyone, Merry Christmas :-).... My Asterisk Box doesn't have a sound card, it is running Asterisk 1.02 Zaptel 1.02 Libpri 1.02 Mpg123 0.59r All compiled from source with kernel 2.6.9-1.6 on Fedora Core 2 Any help would be very much appreciated..... The error I am getting is -- Executing WaitMusicOnHold("SIP/snom-james-849d", "30") in new stack Dec 12 00:27:29 WARNING[409616]: res_musiconhold.c:366 moh1_exec: Unable to start music on hold (class '30') on channel SIP/snom-james-849d == Spawn extension (sip, 098, 1) exited non-zero on 'SIP/snom-james-849d' /etc/asterisk/musiconhold.conf ; ; Music on hold class definitions ; [classes] default => quietmp3:/var/lib/asterisk/mohmp3 ;loud => mp3:/var/lib/asterisk/mohmp3 random => quietmp3:/var/lib/asterisk/mohmp3,-z I also tried doing a default => custom:/var/lib/asterisk/mohmp3,/usr/bin/mpg123 -z -q -r 8000 -f 8192 -b 2048 --mono -s /etc/asterisk/extensions.conf [pstn] exten => s,1,NoOp(Comment Only: Call from ${CALLERIDNUM}) ; Just put a comment in the CLI for info. exten => s,2,SetMusicOnHold(random) exten => s,3,Dial(SIP/snom-james&SIP/bt-karen,45,t) exten => s,4,Hangup [internal] exten => i,1,Playback(invalid) exten => i,2,Hangup exten => t,1,Hangup exten => 098,1,WaitMusicOnHold(5) exten => 099,1,Echo ;simple echo test when you dial 099 on your phone include => outgoing include => sip [outgoing] exten => _9X.,1,Dial(Zap/g1/${EXTEN:1}) exten => _9X.,2,Congestion() exten => _9X.,3,Hangup [sip] exten => 690,1,SetMusicOnHold(random) exten => 690,2,Dial(SIP/snom-james,30,tr) exten => 690,3,voicemail2,u690 exten => 690,102,voicemail2,b690 exten => 691,1,SetMusicOnHold(random) exten => 691,2,Dial(SIP/bt-karen,30,tr) exten => 691,3,voicemail2,u691 exten => 691,102,voicemail,b691 include => internal include => outgoing [from-sip] include => internal /etc/asterisk/sip.conf [general] port = 5060 bindaddr = 192.168.69.1 context = sip disallow = gsm allow = alaw disallow = ulaw nat=disable srvlookup=no localnet=192.168.69.0/255.255.255.0 subscribecontext = sip [snom-james] type=friend secret=<apassword> host=dynamic callerid="James Bean" <690> defaultip=192.168.69.250 dtmfmode=rfc2833 mailbox=690 [bt-karen] type=friend secret=<apassword> host=dynamic callerid="Karen Colomb" <691> defaultip=192.168.69.251 dtmfmode=info mailbox=691
