7777 incoming not working

Thanks, that works now. How do I create these routes with an actual analog DID numbers coming through Sangoma A20001 card. Please let me know or refer me to somewhere where I can find a procedure.
Thanks again

You can set up your FXO's to support DID routing with one DID per Zap channel.
First, modify your zapata-auto.conf to have a custom context for each channel like this:

signalling=fxs_ks
; Note: this is a trunk. Create a ZAP trunk in AMP for Channel 3
context=from-zaptel-custom-3
group=0
channel => 3

signalling=fxs_ks
; Note: this is a trunk. Create a ZAP trunk in AMP for Channel 4
context=from-zaptel-custom-4
group=0
channel => 4

Notice that each channel has a separate, inbound context.

Then add a little code to extensions_custom.conf that looks like this:

[from-zaptel-custom-3]
exten => s,1,Set(DID=7066323343)
exten => s,2,Set(FROM_DID=7066323343)
exten => s,3,Goto(from-zaptel,7066323343,1)

; end [from-zaptel-custom-3

Make one for [from-zaptel-custom-4] also, with either the same or a different phone number.

Now you can set up DID/CID routes for your Zaptel channels.

I am curious about this way.
Or is there any difference between using to zap channel number to route inbound calls?

Have a nice weekend!
