[Asterisk-Users] transfer on a zaptel FXO port

[Jeremy Lowery]

I am attempting to transfer a number that comes in on an FXO port back 
out the same port. The service has 3 way calling and transfer and these 
options are specified in zapata.conf . Some config...

zapata.conf
------------

[channels]
;
context=incoming
signalling=fxs_ks
echocancel=yes
echocancelwhenbridged=yes
relaxdtmf=yes
rxgain=1.5
txgain=1.5
immediate=no
busydetect=yes
callprogress=no
musiconhold=default
usecallerid=yes
callerid=asreceived
transfer=yes
threewaycalling=yes
group=2
channel => 4

[incoming]
exten => s,1,Answer
exten => s,2,Dial(Zap/4,12565554455)


I would assume the system would:
answer the incoming call
flash to the second line
dial the number
flash back to a three way call
hang up

However in the asterisk console I only get

Sep  9 01:49:09 ERROR[87056]: callerid.c:193 callerid_feed: fsk_serie 
made mylen < 0 (-11)
Sep  9 01:49:09 WARNING[87056]: chan_zap.c:5110 ss_thread: CallerID feed 
failed: Success
Sep  9 01:49:09 WARNING[87056]: chan_zap.c:5152 ss_thread: CallerID 
returned with error on channel 'Zap/4-1'
Sep  9 01:49:09 NOTICE[87056]: app_dial.c:715 dial_exec: Unable to 
create channel of type 'Zap'


Is this possible?
