Chan-extra and Zap Channel DIDs

Hi there!

I am looking for help for managing incoming calls from chan-extra channels.
I have a 4 channel GSM OpenVox card which works with chan-extra, and the Dial Strings for example are:
EXTRA/17-1/$OUTNUM$
EXTRA/19-1/$OUTNUM$
EXTRA/21-1/$OUTNUM$
EXTRA/23-1/$OUTNUM$
and they work great!

However, using “Zap Channel DIDs” I have not managed to make inbound calls to work at all… WHICH CHANNEL AM I SUPPOSED TO INSERT IN THE CHANNEL FIELD?

extra-channels.conf

; Span 2: opvxg4xx/0/1 "OpenVox G400P GSM/CDMA PCI Card 0"
group=12
context=from-pstn
signalling = gsm
;pin=1234
channel => 17
context = default
group = 63

; Span 3: opvxg4xx/0/2 "OpenVox G400P GSM/CDMA PCI Card 0"
group=13
context=from-pstn
signalling = gsm
;pin=1234
channel => 19
context = default
group = 63

; Span 4: opvxg4xx/0/3 "OpenVox G400P GSM/CDMA PCI Card 0"
group=14
context=from-pstn
signalling = gsm
;pin=1234
channel => 21
context = default
group = 63

; Span 5: opvxg4xx/0/4 "OpenVox G400P GSM/CDMA PCI Card 0"
group=15
context=from-pstn
signalling = gsm
;pin=1234
channel => 23
context = default
group = 63

How am I going to make “Zap Channel DIDs” to work? Or what dialplan should I write to override this situation manually??

Thanks.

Any ideas guys?
