[Asterisk-Users] How to use a data T-1?

[Steve Jones]

I would say it's only profitable if you're getting ONE T1 instead of
two...??

After all the overhead, for uLaw you would need about 90kbps (give or
take) and for G.729, you would need about 32kbps (give or take).
Therefore, you would have the following:

 

uLaw= about 17 calls

g729= about 48 calls

 

I am trying to start a voip service in my local area and sometimes
seeing these numbers make me wonder how using VoIP for larger companies
could possibly be profitable if you require a $500+ data T1 just have a
decent connect (unless you use g729....?)

		Depends on the codec. If you are using ulaw, you will
only be able to have about 23 calls. If you use g729 you can have as
many as 187 simultanious calls on a data T1.

		 

		Remember, you have 1544Kbs of bandwidth. 

		g279=8Kbs per call

		uLaw=64Kbs per call

		 

		Just do the math.
