You have to upgrade the ATA 186 to atleast 2.15 and this will solve your problem.

One thing I did that helped my faxing consistency was I disabled ECM (error correction mode) on the Fax Machine's that gave me weird error communications messages. This usually fixed it with my ATA running v215 with the default Audio/Connect mode.
What is the 1751 setup for MGCP or H323?

Hi Mike, thank you for your response. The 1751 set up is H323,and the ATAs are with H323 signaling type too. v2.16
