I have configured a b410p isdn card with four NT ports. On the 4th NT port i put a TA which is on Windows os, and run an old isdn phone software(rvs phone). I have configured the extensions.conf file like this
[from-dahdi]
exten => 084766508,1,Dial(DAHDI/g14/${EXTEN})
exten => 084766508,2,Hangup()
exten => _039.,1,Dial(DAHDI/4/${EXTEN})
If from console i call the 084766508 number the phone ring(but if I answer the call fail with 3302 isdn error), but if I call from the isdn phone a test number (200 for example) the software phone put the 039 prefix, so I wrote the extension _039. The problem is the outgoing call is not seen by asterisk, i also write
pri set debug on span 4
but report nothing.
