Transfer from Analog phone

Hello,

I’m trying to transfer calls from an analog phone (connected to a Digium TDM22B) without any success.

Pressing “R” (or flash-hook, as I believe it’s called) doesn’t give me dial-tone. *, # and others don’t work either. It’s like Asterisk isn’t listening? This my zapata.conf:

signalling=fxo_ks
transfer=yes
threewaycalling=yes
cancallforward=yes
echocancel=yes
echocancelwhenbridged=yes
echotraining=400
callerid=asreceived
group=1
context=default
channel => 1-2

I’m in South Africa, if that makes any difference. I’m using a standard tone-dial POTS handset we use here.

Any help much appreciated.

Regards,
Graeme
