Re: Cisco ATA 188 with Fax

Your audio mode and connect mode settings are wrong...

Configuring the Cisco ATA for Fax Pass-through mode

Fax Pass-through mode requires configuring two configuration parameters:

AudioMode

ConnectMode

AudioMode

Description

The AudioMode parameter is a 32-bit value. The lower 16 bits apply to the Phone 1 port of the Cisco ATA and the upper 16 bits apply to the Phone 2 port of the Cisco ATA.

Your audio mode for fax pass throuhg for port1 of the ata should be

0xXXXX0015

and for port 2 of the ata 0x0015XXXX

Your connect mode settings should be...

ConnectMode

Description

The ConnectMode parameter is a 32-bit value. The parameter settings apply to both lines of the Cisco ATA. Configure ConnectMode after configuring AudioMode for fax pass-through mode. Cisco recommends you use the following ConnectMode setting to interoperate with a Cisco IOS gateway.

Recommended Setting

0x90000400

Re: Cisco ATA 188 with Fax

Hi in this parameter:

Your audio mode for fax pass throuhg for port1 of the ata should be

"0xXXXX0015" the "X" must be "X" or it means that I should replace the "X" for another number?

The X must be X, just as it is

Hi,

You dont specify the cisco ATA in a dial-peer.

You configure the ATA in call manager and then you create a dial-peer with its destination-pattern as the directory number of the ATA and session target as callmanager IP address.
