I do implementation in which PBXs are connected to Cisco routers using E&M ports at several sites. A FAX machine is connected to an extension on the PBX needs to communicate with another FAX machine connected to the PBX at another site. The settings of the E&M ports are here:
voice-port 0/0/0
trunk-group e&m
type 5
dial-type pulse
timing wait-wink 800
description E&M-PBX
A voip dial-peers are configured for the destination router.
dial-peer voice 95 voip
destination-pattern 95..
session target ipv4:192.168.125.2
I tried some chnages but it did not work. I will try to configure the codec to G711 and no VAD and no EC on all ports and test it. But it will cost bandwidth.
Do anyone have another solution?

Configure fax relay.

Thank you Paolo
I configured fax protocol pass-through under the service level and it worked. I wait the feedback from the customer if any problems arise.

A better choice is T.38 fax relay.
