[asterisk-biz] PRI vs SIP vs ???

[Don Kelly]

If your decision is based on cost alone, it's likely that the SIP solution
is best.

 

However, if your client requires voice quality and reliability, the PRI
solution will likely win.

 

10-15 concurrent calls over DSL is probably not a good solution.

 

If you're considering a T1 for Internet access, it's probably not a
considerable increase in cost to include PRI. Most LECs offer a hybrid
solution that would include 10 PRI voice channels and 832MB Internet (really
dedicated Internet).

 

If your client is in the Chicago IL USA area the definition of "local" comes
into play. I'm spoiled as I'm located in the Twin Cities MN area-I think we
have the world's largest local calling area. What percentage of your
client's calls are really local?

Gotta client that is moving to a VoIP PBX.  Will need 10 concurrent calls
with ability to grow to 15.

 

Which is better:

 

a)      Traditional PRI with unlimited Local, use Least Cost Routing for
Long Distance via SIP trunks via the Internet

OR

b)      Flat rate SIP trunks which includes unlimited  Local and Long
Distance (no T1 card needed), riding on Dedicated DSL or Internet T1

OR

c)       suggestions?????????
