[asterisk-users] loop-start and ground-start - edited

[Nomad Esst]

Hi list

First of all could you please explain loop-start and ground-start for me? What are they used for?

Next, I have the following configurations:



dahdi-channels.conf :

context=pstn-channels
signalling=fxs_ks
channel=>130
context=phone-channels
signalling=fxo_ks
channel=>127

chan_dahdi.conf :

[channels]
cidsignalling=dtmf
cidstart=dtmf

signalling=fxo_ls
pulsedial=no
usecallerid=yes
context=pstn-channels
channel=>130

signalling=fxs_ls
context=phone-channels
channel=>127

extensions.conf :

[pstn-channels]
exten=>_.,1,Dial(DAHDI/127/${EXTEN})

[phone-channels]
exten=>_.,1,Dial(DAHDI/130/${EXTEN})

/dahdi/system.conf
fxoks=125-128
fxsks=129-132

I can't hear the dial tone from the phone with these configurations. As soon as I comment "signalling" type in chan_dahdi.conf, dial tone comes up. What's the problem with these configurations?
