Problems with zaphfc



what I want to do is to set up an VOIP-Gateway for my ISDN phones. My hardware consists of one AVM FritzCard USB and a HFC-chipset based ISDN card. The HFC card is connected to a NTBA with “crossed ISDN - wire”. The telephone is connected to the same NTBA with normal wire. If I pick-up at the phone I get an Installation-error on its display. Trying to call the phone using asterisk shows this:

*CLI> Dial 47756385 *CLI> -- Executing Dial("ALSA/default", "Zap/g1/47756385") in new stack -- Requested transfer capability: 0x00 - SPEECH -- Called g1/47756385 -- Channel 0/1, span 1 got hangup, cause 42

…but the telephone isn’t ringing… Any help apreciated! Thanks Michael

here is my config:


[test] exten => 47756385,1,Dial(Zap/g1/${EXTEN}) exten => s,1,Playtones(500/200,0/500)


switchtype = euroisdn

signalling = bri_net_ptmp

pridialplan = local
prilocaldialplan = local

echotraining = 100

callprogress = yes
busydetect = yes

usecallerid = yes
usecallingpres = yes

group = 1


[code]# hfc-s pci a span definition

most of the values should be bogus because we are not really zaptel



cat /proc/zaptel/1
