RE: iSeries Voice Over IP -- MIDRANGE-L

In my experience 56k for voip is not enough close to enough.  If you
toss in voice mail on top of the system you are adding even more
overhead.

It can be done, but it takes work and you need to examine your network
infrastructure closely, ie: intelligent switches at each location, ample
bandwidth, and I would not personally use anything but cisco routers for
this.  Although I do not like their voip phone systems, their routers
handle the traffic extremely well.

It all depends on what you are trying to accomplish.  Voip can provide
you with additional resources and enhanced services but if your only
goal is to save money you will be somewhat disappointed.

Subject: Re: iSeries Voice Over IP


I've been working where we put in VOIP some years ago. For the 
technology programming, i.e. the parts that make it work, I think it's 
hard to beat a dedicated IP-enabled "voice server" (I guess you could 
call the replacement for PBX systems), that supports the voicemail and 
the phone lines and all that, connecting to a router that communicates 
with routers and similar phone systems on the other end.

At the central office, we had a dedicated router for voice, another for 
data, and they broke up the IP packets for each branch. There was 56K 
dedicated for each branch, and the traffic split between dedicated 28K 
for voice, 28K for data. 

Putting the AS400 in the middle would've put it "in the way".

On the other end, the router split the traffic back out. (This handled 
by outside support for configuring those routers in this case).  The 
voice had about 26K dedicated for each branch (one maybe two max calls 
at a time).

The AT&T tech who set up the phones said they now call the phones on 
your desk "voice terminals".

I think it would be useful to have better interfacing, or technical 
software packages or IP-enabled API's, for feeding usage data to the 
iSeries system for supervisory and accouting use. After all, they're 
talking about putting IP into everything, airborne dust specks included.
