[cisco-voip] Configuring first VG224: MGCP vs. SCCP configurations

[Lelio Fulgenzi]

Thanks Nate....I think this would be a good discussion. I too would probably agree with a stack of VG224s with SCCP for phones and a stack with MGCP for FAXes and modems. However, I'd agree on this only if (a) the configuration down the entire voice path was as simple and (b) I could get SuperG3 support. Otherwise, I still don't see the advantage. Especially if the fax deployment on the campus is simple fax machines, not fax servers etc. 

What are the advantages of T.38? Will they work with MGCP gateways or do they need H323? Are H323 VG224s even better?

I guess I am the only one that is going to disagree. 



I initially configured all of my gateways SCCP when that protocol was available. It has the best telephony feature set. However, I have found that those features aren’t used most of the time. 



The biggest use of analog in my mind is faxing. It seems like the future of faxing is T.38. While SCCP supports Cisco proprietary NSE based T.38, try and integrate that with even Cisco’s OEMed fax server. 



So I recommend MGCP for at least your fax ports on your VG224 so that you can run protocol based T.38.

I agree. If you are only using them for phones, go for SCCP. Even for modems and faxes, you can use modem/fax passthrough and things work well. 

Check the list archives for information about how MGCP is a better option for alarm systems that convey contact information. 

P.S. if you are deploying a few, consider the four-pack. it's cheaper

SCCP is superior as a control protocol for VG224s as it not only makes configuration of the ports extremely easy, it also enables a lot more features that are otherwise unavailable if MGCP is used as a control protocol. 

SCCP essentially makes the 24 FXS ports into phones you can configure just like any other IP phone within CCM.

Currently we have many old VG248 dinosaurs in our shop. So 
we started the configuration of our first VG224. The question has been raised 
as to use either MGCP or SCCP. Which one is the best and why? 

Thanks. 

Rob
