I am playing with the dialplan to get it working and I have a challange with this error. I can't find what it means on the wiki :( Any sugestions would be helpful at being able to forward it to the SIP phone if it is online and avaliable but then let that fail and drop into voicemail if it is not online or is busy. cheers David -- Executing Dial("IAX2/firefly@89280250/3", "SIP/800|5") in new stack Dec 21 00:15:57 NOTICE[3922]: app_dial.c:800 dial_exec: Unable to create channel of type 'SIP' (cause 3) == Everyone is busy/congested at this time -- Executing WaitExten("IAX2/firefly@89280250/3", "") in new stack The Extensions.conf file for that section is exten => s,1,Wait,1 exten => s,n,Answer exten => s,n,DigitTimeout,3 exten => s,n,ResponseTimeout,5 exten => s,n,Dial(SIP/800,5) exten => s,n,Waitexten exten => s,n,Playback,voicemail/default/801/unavail exten => s,n,Voicemail,801 exten => s,n,Goto,t|1 and I have in sip.conf [800] type=friend regexten=800 username=800 secret=password callerid=800 host=dynamic ;dtmfmode=inband mailbox=800 nat=yes canreinvite=no qualify=yes disallow=all allow=gsm allow=speex allow=ilbc allow=ulaw allow=alaw
