I have a Cisco CallManger 4.2 with 2800 series gateway and ATA's.
E1 is connected with the gateway.Now when i try to send faxes from my fax machine through the ATA some times the fax reaches the destination
correctly and sometimes not .Same is recieving some times it works and sometimes it does not .
I have not applied any special configuration on E1 for FAX calls .Normal config whcih is
dial-peer voice 100 voip
description Forward Inbound Calls to CM (Subsriber)
voice-class codec 1
voice-class h323 1
session target ipv4:10.7.0.13
Do i need to configure anything on the gateway or ccm or ATA to correct this issue?
