Hi all, I am close to giving up. I got my hfc-s up and running with dahdi [code]trunkgroups] [channels] language=de switchtype=euroisdn pridialplan=unknown prilocaldialplan=unknown internationalprefix = 00 nationalprefix = 0 ;localprefix = VORWAHL ;privateprefix = VORWAHL+MSN unknownprefix = priindication = outofband facilityenable = yes usecallerid=yes callwaiting=yes usecallingpres=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes canpark=yes cancallforward=yes callreturn=yes immediate=no echocancel=yes echocancelwhenbridged=yes echotraining=yes callgroup=1 pickupgroup=1 mohinterpret=default mohsuggest=default group=1 signalling=bri\_cpe\_ptmp ; p2p TE mode =\> bri\_cpe ; p2mp TE mode =\> bri\_cpe\_ptmp ; p2p NT mode =\> bri\_net ; p2mp NT mode =\> bri\_net\_ptmp context=from-isdn channel =\> 1-2 [/code] as you can see in the extensions below, i tried many things and what i could observe was only the following: 1. If I ;comment out the from-isdn section completely, the system will ignore every incomming call 2. whatever I try to configure, asterisk will answer with “Channel ‘DAHDI/i1/0151123123123-1’ sent to invalid extension: context,exten,priority=default,12345,1” 3. even the noop instruction creates “Channel ‘DAHDI/i1/0151123123123-1’ sent to invalid extension: context,exten,priority=default,12345,1” [b] Iam trying to make the asterisk to work like an isdn phone: - incomming calls should ring on sip 1000 - it should be possible to also pick up the calls on the external ISDN-telephone, so no waiting line etc[/b] [code][general] static=yes writeprotect=no ;autofallthrough=no ;extenpatternmatchnew=no clearglobalvars=no ;userscontext=default [internal] ;include =\> stdexten ; ; We start with what to do when a call first comes in. ; ;exten =\> s,1,Wait(1) ; Wait a second, just for fun ;exten =\> s,n,Answer ; Answer the line ;exten =\> s,n,Set(TIMEOUT(digit)=5) ; Set Digit Timeout to 5 seconds ;exten =\> s,n,Set(TIMEOUT(response)=10) ; Set Response Timeout to 10 seconds ;exten =\> s,n(restart),BackGround(demo-congrats) ; Play a congratulatory message ;exten =\> s,n(instruct),BackGround(demo-instruct) ; Play some instructions ;exten =\> s,n,WaitExten ; Wait for an extension to be dialed. ;exten =\> 2,1,BackGround(demo-moreinfo) ; Give some more information. ;exten =\> 2,n,Goto(s,instruct) ;exten =\> 3,1,Set(LANGUAGE()=fr) ; Set language to french ;exten =\> 3,n,Goto(s,restart) ; Start with the congratulations exten =\> 1000,1,Goto(default,s,1) exten =\> 1001,1,Goto(default,s,1) exten =\> 1002,1,Goto(default,s,1) [from-isdn] ;exten =\> 12345,1,Dial(SIP/1000,120) ;exten =\> 12345,1,Goto(default,s,1) exten =\> 12345,1,noop() exten =\> 12345,2,Set(LANGUAGE()=de) ; Set language to German ;exten =\> 12345,1,Answer() ;exten =\> 12345,2,Wait(2) ;exten =\> 12345,3,Playback(hello-world) ;exten =\> 12345,4,Wait(2) ;exten =\> 12345,5,Hangup() [globals] CONSOLE=Console/dsp ; Console interface for demo ;CONSOLE=DAHDI/1 ;CONSOLE=Phone/phone0 IAXINFO=guest ; IAXtel username/password ;IAXINFO=myuser:mypass TRUNK=DAHDI/G2 ; Trunk interface TRUNKMSD=1 ; MSD digits to strip (usually 1 or 0) ;TRUNK=IAX2/user:pass@provider ;[FREENUMDOMAIN=mydomain.com](http://FREENUMDOMAIN=mydomain.com) ; domain to send on outbound ; freenum calls (uses outbound-freenum ; context) [/code] ---

add a line to your from-isdn context like exten =\> \_X.,1,Noop(caller ${CALLERID(all) called ${EXTEN} TTFN) exten =\> \_X.,n,Dial(SIP/1000,120) ---

Hi, thanks before you posted, I found out that this did the trick, i dont know why ```auto [default] include => from-isdn include => internal ``` ---
