PRI span restarting… here’s how to remove those warnings..

Found this here... thought I should archive it...

I often get emailed by people, wondering if their T1 card is having problems. Their email goes something like this:

The following stuff shows up on the asterisk console from time to time... Is that anything to be worried about? Is the card malfunctioning and restarting? Is this dropping all the current calls when this happens?
-- B-channel 0/1 successfully restarted on span 1
-- B-channel 0/2 successfully restarted on span 1
-- B-channel 0/3 successfully restarted on span 1
-- B-channel 0/4 successfully restarted on span 1
-- B-channel 0/5 successfully restarted on span 1
-- B-channel 0/6 successfully restarted on span 1

There's no need to panic :-) Asterisk, be default, will restart any idle B channels every hour. Here's the relevant section from zapata.conf:

; PRI resetinterval: sets the time in seconds between restart of unused channels, defaults to 3600
; minimum 60 seconds
; some PBXs don't like channel restarts. so set the interval to a very long interval e.g. 100000000
; or 'never' to disable *entirely*.
;
;resetinterval = 3600

To keep Asterisk from doing this, simply set "resetinterval=never" in zapata.conf, and restart Asterisk.
