Summary:                    PRI link fails dropping all the active voice
channels
Description: 
Sometimes Asterisk resets D-Channel port of the PRI interface and all the
active communications fall down. This could take down until 30 voice
channels. We cann't identify when this happens. During a week we had no
problems but other weeks we have had errors all the days and several times
a week (i.e. one day 8 times).

[Jun 19 12:29:40] WARNING[14561] chan_zap.c: No D-channels available! 
Using Primary channel 16 as D-channel anyway!

The software realeases we are using:

* Asterisk 1.4.19
* Asterisk Addons 1.4.7
* LibPRI 1.4.4
* Zaptel 1.4.10.1

We are having this problems with Telefonica, a telco company from Spain.
We have being working with its technicians and they say that is the
asterisk which resets D-Channel and not the network.

We have reproduced this problem with two different PRI cards: TE110P and 
TE2XXP.

In the uploaded configuration files span 1 is connected to telco and it's
the interface that is having reset problems
