Although I have not used it as a customer, two things I would caution you about - make sure you use the latest IOS software available, and also note that there are only 6 DSPs in the chassis, which is enough for 24 total voice channels. So that includes any PRI and analog cards that you use, plus the 8 port FXS that comes in the box. So make sure you plan voice channel capacity appropriately.
Unless you need the FXS port density, I would reccomend a 2600 and a 3524 over the 4224. We have some issues with the two we deployed in August, but TAC promises new IOS releases in December will fix our issues.
We have problem with a 4224 running 12.1(5)YE2 - if you connect a fax to an fxs port the port no longer works properly - outgoing calls you just get dropped backed to dial tone every time you press a digit, incoming calls is setup ok but you get one way audio which is badly distorted. Need to reload the 4224 to clear the problem. (Anyone else seen this problem)
We have three deployed. Two work just fine, however one had an issue with the PRI coming in from telco. Everytime a call would come in, the 4224 would reset. I'm running on a development version of the IOS and it is working better now, but we are still hammering out a few bugs. Like I said, out of three, two worked as advertised without any problems.
FYI, although I have not used a very wide deployment scenario (since I have no actual customer installations), we have done some work with the 4224 and found YE3 code to be much better than previous versions.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
