asterisk users - Apr 2005 - Asterisk becomes after one month unstabled

Asterisk is on my box now running about one month without any troubles.

Since two days I got troubles:

1. The Zapta card (2 FXS, 2 FXO) suddenly does not like one phone. It 
simple does not supply with a dial tone. You cannot dial. You can reach 
it, better say, you can dial it, it rings, but no sound.

I reloaded and even restarted * without success. Than I removed the 
module and inserted it again, ... restarted * and it works again.

2. During a call the rtp suddenly stops, no sound in either direction. 
To redial from the sip phone was impossilbe, since no dial tone 
available. CLI did not show anything, but hitting enter gives you the 
next *CLI> line. Reloading did not help. No dialtone on any phone, 
restart did help.


Both situations happend within 24 hours.

What could be the reason? Is there a mechanism to minimize down time?

Exact same situation with analogue phone happened to me. Apparently,
there are still some serious bugs in zaptel (possibly in firmware of
Digium cards, even). As far as analogue phones are concerned, my
experience is that IAXy is much more reliable than TDM cards.

Yup, mine does that too after a couple of weeks.  I have a script to
automatically unload and reload Asterisk and the modules.  The script I use
is in the Wiki, near the bottom of this page:
http://www.voip-info.org/wiki-Asterisk+automatic+daily+restart
That's a band-aid, of course, but until Digim tells us all how to fix their
cards, that's about the best we can do.
