Fax from ATA not detected

Unanswered Question
Sep 19th, 2007

Hi,

I've a customer with CCM 4.1 and several ata; almost all fax are working fine exept when they must be intercepted as fax call.

I'll try to be more clear;

In some place there are "devices" that collect both voice and data call from fax connected to ata. If the call is voice is sent to a phone, if the call is data is sent to an analog fax machine.

What we see is that data calls are not correctly forwarded. I've seen http://www.cisco.com/en/US/products/hw/gatecont/ps514/products_administration_guide_chapter09186a00800c4d1e.html#97426 where it's explained FAX-PASSTHROUGHT are sent as voice call... could be this the trouble ? I've to force fax as FAX MODE ?

Any suggest ?

Many thanks

Luigi

I have this problem too.

Hi Luigi,

Have a look at the following;

Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator's Guide (SCCP) (2.15.ms, Rev B0)

Configuring and Debugging Fax Services

http://www.cisco.com/en/US/products/hw/gatecont/ps514/products_administration_guide_chapter09186a00800c4d1e.html#1016012

Configuring and Troubleshooting the Cisco ATA 186 with Fax

http://www.cisco.com/en/US/products/hw/gatecont/ps514/products_configuration_example09186a00800d698e.shtml

Configure Fax Detection Method on the Cisco ATA 186

Use a web browser and go to http:///dev (for example, http://172.16.104.117/dev) in order to configure the Cisco ATA 186 using the web interface.

You must configure these parameters in order to configure the Cisco ATA 186.

Audio Mode

bit 2 (18)=0 Enable detection of FAX CED (answer) tone and switch to FAX mode for the rest of the call if the tone is detected.

Hope this helps!
