ATA 186 and FAX RELAY

[r.earle]

Has anyone using fax pass through been experiencing problems with inconsistent faxes, cut images and the like? I have been having this issue and was wondering if going to fax pass through would help our situation. Anyone do this? that could give me some insight?

Thanks,

Ron

I had the same problem (inconsistent faxes, cut images.. etc ) and I resolve my problem whith the new ATA186-I1

The issue is "CSCdv90018"

Symptom:

Fax passthrough fails when operating the Cisco ATA 186 in fax passthrough or fax mode at a transmission rate of 14.4Kbps or V.17 with a Cisco IOS-based gateway.

Condition:

This fax passthrough issue affects all VoIP protocols (H.323/SIP/MGCP/SCCP) when the fax transmission rate is higher than 9.6Kbps.

Workaround:

Fax passthrough enhancements have been made in the software but new hardware revisions of the Cisco ATA 186 (ATA186-I1 and ATA186-I2) are required for fax transmission up to 14.4 Kbps.

Thanks for your response. We are using ATA186-L-I1 though and still we experienced this issue at initial install. Seems to be operational now. Though we are not sure what we did or if it was a coincidence. The problem could have been the fax machine itself.
