FAX through VG224

Unanswered Question
Dec 26th, 2007

Hi All,

I am using VG224 . The analog port output of FXS port on VG224 is connected to FAX machine.

Problem is that I am not able to send ISD fax messages when FAC is enabled on ISD route pattern.

After the FAC is removed, I am able to send the FAX.

Pls. suggest if anybody has faced this problem earlier.



I have this problem too.

Cisco 26xx, 36xx, 37xx, and AS5300 support gateway-controlled T.38 with MGCP from Cisco IOS Software Release 12.2(11)T. However, it is not supported in the Cisco CallManager network until Cisco IOS Software Release 12.2(11)T3 where "forced" T.38 mode has been added.

N/A with Cisco CallManager.

When using Fax/Modem pass-through between Catalyst 6000/VG248 and Cisco IOS gateways, you need:

Voice Gateway Routers: Cisco IOS Software Release 12.2.11T or later is recommended

VG248: 1.2.1

For Catalyst 6624, the loads A002030139S1 and A00203010041 are recommended.

For Catalyst 6608, the loads D004030145S1 and D00403010047 are recommended.

3.2.(2c)SpD include loads D004030145S1 and A002030139S1.

3.1(4)SpA and 3.2(2c)SpF include D00403010047 and A00203010041.

You must have Cisco CallManager version 3.1.3a or later to use fax pass-through mode on the Cisco ICS 7750.
