VG224 Recommendation

Unanswered Question
Mar 28th, 2008

We are installing a two site UCM Business Edition solution. Main site single gateway will be setup as h323 gateway (due to need to run T.37/tcl scripts - to get faxes to emails).

We also have a vg224 at main site that will have faxes, modem and polycom conference stations off it. My question is, is the easiest way to set this vg224 up is as a sccp gateway registered to CCM? If so, can it still allow modem/fax passthrough? Or is modem/fax passthrough only allowed on h323


If you recommend h323 for VG224, do I simply point all dial-peers to the h323 main gateway that will have our PRI connected to it? So aside from virtual dial-peers that are created for devices connected, is it just voip dial-peers pointing to the h323 gatway (and not to CCM)? We do want supplementary services for analog phones/conference stations.

thanks in advance,

I have this problem too.

Use MGCP for VG224, faxes work fine then.

What about modem passthrough? I assume yes but need to be sure.

thank you PK

I'm looking for a config for a VG224 Gateway.

Can anybody provide me a configuration example, for MGCP or SCCP?

I like to configure the easiest way, I think it will be MGCP.

The Gateway will be installed only for Fax Machines.

Thank you for your help.

Yes, it seems to be working fine. I can send and receive faxes.

One last question about QoS...How I need to setup Qos on this Voice Gateway?
