I have a fax machine on an ATA-186 and it has been working fine for over 8 months until last week.
You can call the fax externally using a local or long distance number, but you cannot call the fax on net
through our network, it just rings.
As a fix for now, I have given the fax a different number and created a CTI route point forwarded to the
fax machines real number using the local number.
Since everything looks fine on Callmanger and I can see the number hit the PRI using debug are there
any settings on the fax that could cause this strange issue? Has anyone else seen this?
