firstly you must thoroughly check your existing IP network ( for Voice integration I mean ) ie bandwidth, delay, relability. As mentioned earlier, scalability is something that is a major aspect, also flexibilty!
The planning and design of this entire network has to be well thought out! like say if you are going to later on go to implement VoFR or VoATM!
Complexity of VoIP is another interesting part to have a look at! it is much better than VoFR or VoATM but can be quite difficult to implemtent, again this relates back to the Design issues!!
After all this is done, all you have to look at is the H/W needed for your design!
Well I guess these are just the basics, but a good thing to always look back upon!
Here is something to keep in mind if you will be deploying VOIP over Frame-relay: The Frame-Relay Fragmentation feature is not available on all model of routers, regardless of the IOS revision being used (12.x and so on)
You may find yourself replacing routers in the cloud so they can run frame-relay fragmentation, even if they do not run VOIP, simply because they share an aggregation point (common physical interface) that other VOIP routers are pointing to.
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...
