Summary:                    [patch] NT over PtMP for BRI
Description: 
Ok, this patch is a naive test i made, but very very limited a bit is
allready working. You can call from one connected ISDN device (i used a
ISDN/analog adapter DeTeWe TA33) into chan_dadhi. That's all, nothing more.
You can't call from chan_dadi to the ISDN device or connect multiple isdn
devices.

Also chan_dadi jumps directly to the s-Extension when you lift up the
phone. And dont give you dial tone or wait for digits. But i was pleasantly
surprised that NT-ptmp is working anyway.

Let's start to work on this, to finally ditch bristuff and chan_misdn

check attached file call_to_bristuff_ast_ok

The log when i call to an bristuffed *1.4 is working, and lokks a bit
diffrent:
the CONNECT ACKNOWLEDGE message we send now looks:
> Informational frame:
> SAPI: 63  C/R: 1 EA: 0  <---- SAPI should be 0? 63 is for TEI
management
>  TEI: 064        EA: 1
> N(S): 003   0: 0  <---- What function this line have?
> N(R): 005   P: 0  <---- What function this line have?

And the call to mISDNuser:

>  TEI: 064        EA: 1
