asterisk users - May 2005 - PRI timing problems: Fax & Voice

I've been trying to get PRI -> Email Fax to work for some time now.
Several
months. Got newest everything and still some pages come out missing an inch
or two.

It was recommended to me to change my zaptel.conf so that span #1 used
itself as primary sync source. (It was set to 0).

I made the change and now FAXES LOOK PERFECT!!! 100+ pages and not a single
problem.

The problem now is, I get this error every so often:

May  4 10:57:04 WARNING[25650]: chan_zap.c:4394 my_zt_write: Write
returned -1 (Resource temporarily unavailable) on channel 2 - audio may have
been lost

When the span was "0", I NEVER got that message. I haven't heard
any
complaints from the other office mates that use the PRI for voice, but the
error just bothers me.

What is the real difference between "0" and "1" on the span
timing?

Thanks,
Matthew

I think that something in asterisk (not zaptel) changed in the last week to 
create this problem; see my last message to -dev.

all that the clock span means is what span * synchronizes to.

clock of 0 means do not try to synchronize to the clock on this span
1 means this span is my primary clock sync source
2 means that if the span with '1' is down, use this one
3 means if the spans with 1 and 2 are down, use this one

etc.
