Summary:                    [patch] v.110 dialin support for ISDN channels
Description: 
Many years ago I wrote app_v110.c for use with mISDN channels. It was
included in the Beronet app_bundle which I thought they were going to
submit after chan_mISDN was merged:
http://www.asteriskguru.com/archives/asterisk-dev-re-chanmisdn-in-asterisk-beta-2-vt60496.html#170458

Someone's now made it work with Zap channels too, and is asking why it
didn't get merged.

I'll attach my original code for reference and state that I have a
disclaimer on file. Hopefully I can let the person who ported it to Zap
take care of submitting an up to date version which is tested with current
Asterisk code.

tomzack: you did not say which app_v110.c version you tried. Also, you must
test with Asterisk trunk svn. I don't plan adapting this for other Asterisk
version than trunk.

I just attached a new patch, whith a fix in chan_dahdi.c to by-passing
ast_dsp_process call when the call is digital, that seemed to be what was
breaking the v.110 stream badly. You should try with patch
app_v110-rev-221968.patch

I discussed the by-passing of ast_dsp_process with kpfleming on IRC and he
thinks is reasonable, so that little fix should not break anything else.

I don't know anything about app_pppd.
