Hi Guys,
Our Customer have any sites and the sites with FXO the Fax work. There is a site that we have E1 R2 the fax don't work, appear the message "communication error". Ask, there is any specific configuration in the Gateway or ATA for the fax work?
Thank You,
Wilson

If H323 connection between the two AS5300 gateways is G.723x or G.729x, the FAX always fails to transfer the FAX message to remote FAX machine. If I set Codec G.728(16kbps) or G.726 (whatever Spec) on Local Dial-peer voip, the local FAX never transfer to final FAX machine. ( Local FAX often detect response tone(beep) from remote FAX, But it fails always with communication error message from remote FAX.

Hi Ebreniz,
I am sorry I don't understando that you speak. The solution is CallManager 5.1.1 and any sites have Gateway 2811 with E1 R2 and the ATA connected in Switch in a one side and tax connected in the ATA.
Thank You,
Wilson

Please send output of "show controllers e1", you might have slips prevent the fax to work.
That is due to lack of "network-clock-participate" and "network-clock-select" commands.
Hope this helps, please rate post if it does!

network-clock configuration is OK. Now check:
For how to configure and troubleshoot ATA for fax.

Hi Bevilacqua,
I verify the document that you send for me where it's mention that the codec for E1 should be G.711A-law. In the CCM was G.711u-law, when I change the parameters in the in the option gateway in the CCM, the gateway stop to do external calls.
Wilson

g.711u or a doesn't change. Leave it as it is and check all other parameters.
06-16-2008 06:44 AM
Hi Bevilacqua,
The problem is occuring because the Fax is a Super 3G and operate with 33,6kbps and the ATA operate with 9,6kbps. I am waiting the Customer change for executed tests.
Thank You,
Wilson
