Summary:                    [patch] channel alarm set when a channel is opened
Description: 
If a channel alarm is already set when a channel is opened by Asterisk,
whose responsibility is it to check for the alarms?

1. The channe l driver should detect that and re-send alarms on zt_open

2. Zaptel should  send an alarm event at channel open time. The
applicaiton opening the channel should then be able to read those events
and will have the proper information.

3. The application should read channel alarms at channel initialization
time. No need for Zaptel to send extra events.

As senseless as (1) is, it has been used in practice by the xpp d FXO
module driver. I figure you all agree with me it is not the way to go.


The behaviour with regards to span alarm seems in Asterisk seems to be
(3).

Attached are patches implementing both (2) and (3)

I wish I had the transcript from the IRC chat you, kpfleming, and I had on
this, but I believe the result was to put it in asterisk and not zaptel.
