color:#1F497D'>I have a remote site (50 users) trunked with a PRI to a 2821
router. I use ata186’s for fax machines. The users at this
site are reporting that many of the folks that used to be able fax to them
prior to moving in cannot now that they are on an ATA. The fax machine
reports “line failure” or “no fax detected” when this
occurs. Other sites can fax in no problem. The gateway is set up
for fax-pass-through and DTFM relay “Current GW Config” (?) and the
DSPware is current (28x). The ATA parameters of course are cryptic.

is painful to troubleshoot. I was looking for thoughts and experiences on
resolving these types of issues. <o:p></o:p></span></p>
