I have two fax machines that are connected to a VG224 and both those are having intermittent issues. Incoming fax fails on the remote end and an error is generated but at the remote end but for outgoing fax, no errors are generated. The only way to check if the fax was sent successfully is by calling the customer and asking if the fax was received. Please help.

Which type of router and line do you have on the router/GW ?
03-11-2009 12:36 PM
The VG224 is uplinked to a 2851 with a PRI in it.

Check that you have:
network-clock-participate wic 0
network-clock-select 1 T1 0/0/0
Or change "0" as needed.

Any help?

What protocol are you using on both the vg224 and the 2800?
If it's H323/SIP/SCCP try this:
voice service voip
fax proto none
modem pass nse code g711u
Check 'show controllers t1' for slips (anything other than 0 in the counters is bad), and check 'show call active voice brief for packet loss or jitter - use attached doc for help).

Also ensure that the codec being used for the fax calls is G711 at all stages and the the faxes themselves are not "super G3" or similar enhanced data rate devices.

Hello Carl,
The protocol is G.711 at all stages and the faxes are not super G3.

Hello Nic,
The VG224 and the gateway uses MGCP. There are no clock slips happening.

I have tried calling the fax number and it looks like its hitting the 0/0 dial-peer and not the dial-peer attached to the fax machine. Is this normal? I dont see any jitter, latency, packet drops etc.
