VIC2-2FXS Fax, fax-relay problem

Hi,

Scheme:

PSTN Fax -> ISDN BRI -> FXS

I have CME 7.1 with VIC2-2FXS on 2801 router. I have tried to configure the port in both ways as sccp controlled and just with pots dial-peer that points to the interface.

The most successful test I have achieved with fax passthrough mode but still communication errors.

I tried to do exact what is written in the document:

Supplementary Services Features for FXS Ports on Cisco IOS Voice Gateways Configuration Guide

The fax machine is old style panasonic which work wonderful with directly attached PSTN line.

The call is fully processed only from the router. There isn't VoIP transition in the scheme.

Finally my question is: Is there somebody who have successfully configured and tested scheme like mine?

Thank you.

Best Regards,

Zdravkov

Configure network-clock-participate and network-clock-select for the BRI interface.

Hi Paolo,

Thank you for your answer. In my configuration I have network-clock-participate but network-clock-select is missing. There isn't any errors on the ISDN interface. I'm going to test the fax on Monday.

Do you think that can be the reason for my problems?

Best Regards,

Zdravko
