Single DID for voice and fax

[rockstar72]

I am looking for a solution where I am able to have a single DID number that can be used for both voice and fax calls.  Essentially, the system needs to detect the signaling from the fax call and route it to e-mail rather than ringing the phone.  The same DID needs to route voice calls to the phone, however.  I am currently using Comm Manager 7.x and H.323 gateways.  I've been told that there is a solution from I3 that can do this.  Can we do it with Cisco?

As I'm researching, it looks like this is possible using a TCL script in the voice gateway.

Does anyone know if there is any other way to accomplish this?

Hello,

The new TCL fax detect script that has T.38 support is version 2.1.2.3 and it is downloadable from the CCO software center for valid cisco.com users. Updated documentation for the fax detect script and its T.38 support is available for IOS releases 12.4 and 12.4T.

Prior to TCL 2.1.2.3

Prior to April 2009 and the release of TCL version 2.1.2.3, Cisco did not provide a T.38 fax detect script similar to the T.37 fax detect script that is available for download on CCO. Therefore, the alternatives for customers looking for a T.38 fax detect script prioir to version 2.1.2.3 are as follows.

• 1) If the customer is proficient at TCL then the existing T.37 fax detect script can be altered for T.38 fax relay. The one drawback to this approach is that now the customer has to support the script as it has been altered.
• 2) Customer can contact Cisco Developer Services to alter/create the T.38 fax detect script. Cisco Developer Services will now support the script but there is a charge for this service.

Be aware that fax detect is also referred to as Single Number Reach (SNR) because it provides the ability for fax and voice calls to share a single inbound DID.You should also be aware that TCL scripts such as fax detect are not supported on MGCP voice gateways.

Hope this helps.

Cheers,

Jose
