[Asterisk-Users] Problems with faxing via TE405P/Asterisk

Fri Jun 25 11:43:01 MST 2004

Ok, may have got to the bottom of this.

The te405P was sharing interrupts with a via82cxxx audio chip, that was
being used to generate the music on hold for our existing pbx.

Having now shut down the music on hold the system will now run correctly
with telewest as the master and the gdk as the slave.

This came about due to the high number of missed IRQ's, it seems as though
the 2.4.22 via driver is none to selective about what it grabs.

I'll leave it running over the weekend and see how it holds up.

Hi Steve,

How bizarre, your config doesn't look like it should work too well and
certainly doesn't look like it should improve your fax problem!

I assume that pri_cpe is set for span1 and pri_net for span2 ?

Maybe, just maybe, Telewest reconfigured your PRI to look for clocking from
your CPE but I've not encountered that configuration before. Try and leave
the current config up for as long as you can before you return it to
production mode and watch the CLI/logs to see if you get any sporadic clock
slips (within a couple of hours I'd expect at least one episode of
messages).

One last thought, did you bounce the system after you made the changes to
zaptel.conf or did you just reload * ?

HTH

They look odd to me for sure, I'm certain (99.9%) that Telewest would not
clock off of us, but as far as I can see, the current config (which allows
the GDK to send and receive faxes) has no external clocking???

Here's the current config:

span=1,0,0,ccs,hdb3,crc4
span=2,0,0,ccs,hdb3,crc4

Here's the original config which I took to mean that Telewest provided clock
and span2 clocked off span1?

span=1,1,0,ccs,hdb3,crc4
span=2,0,0,ccs,hdb3,crc4

(Span1 goes to Telewest - our Telco provider, span2 goes to our current PBX,
a GDK-186)

Steve,

your config description (timing) does sound odd. Could you re-post your
revised config files?

Thanks

I've changed the zaptel.conf to set both as internal, and it now seems to
work, which is backwards to the config I thought it should have been, I
would have thought that the Telewest PRI would have been 1 and the GDK 0?

Can somebody confirm that this is the correct definition for timing, if it's
a +ve number then it's external clocking with the lowest 1 being the highest
priority.

All spans are clocked relative to the external source and the external
source selected is the lowest priority number that is currently being
clocked?

I'll experiment some more.

This is most likely to be a timing issue. You need to make sure your
asterisk is get timing from your telco, and provide timing for you gdk
pbx. /etc/asterisk/zaptel.conf is the place to look.
