Hi All, I have several ATA 186's at a location that I'm using for analog fax lines. This site complains about fax's dropping and a multitude of other problems with faxing. I'm trying to narrow down what may be the problem. I kind of think that its the fax machine, the site has about seven of the same fax machines and sporadically all have complained about inconsistent faxing. We have a full PRI, running Call Manager 126.96.36.1990-1 business edition, MGCP as our Gateway protocol, SCCP as our device protocol. I'm wondering if my ATA configuration has something to do with this. I'm attaching a screenshot of the "audio" configuration of one of the ATA's that are having issues. Is this the correct Codec that I should be using? I'm also using âfax pass-throughâ and have enabled modem âpass-throughâ on my gateway configuration in call manager.
Thanks for the help,
