asterisk users - Feb 2018 - Features.conf and variable length DTMF sequences

Hello,

I have an Asterisk 13-enabled system.

1. Using features.conf application map (or something else), is it possible
to define a single map matching several DTMF sequences, such as in the
imaginary example bellow ?

features.conf:
foobar => _*123.,peer,Gosub,"foobar,s,1"

_*123. would match DTMF sequences *1234 or *12345 or anything starting with
*123



2. I used the mapping bellow:
foobar => *123,peer,Gosub,"foobar,s,1"

In my diaplan, I edited something like:

[foobar]
exten = s,1,Read(FOO,silence/1)
same = n,Noop(FOO is ${FOO})


When I originate a call (with "channel originate Local/1 at test/n" or
"channel originate Local/1 at test") to an other Asterisk box which
sends a
*123ww456 DTMF sequence, I can see that:
- the DTMF is coming in,
- its *123 prefix is recognized and triggers my foobar routine (see above)
- application Read is executed,
- next DTMF digits are coming in but are not read by Read application as if
I was reading on one channel and digits were coming in an other channel.

Any help on this ?


Best regards
