voice environment to IP
Consolidated 600 disparate
PBXs under common
management and control
platform
Connected platforms into their
SIP trunk services

Understanding PRI toll and
access charges
Access fees reduced
Local outbound toll charges eliminated
LD outbound toll charges eliminated
On-net calls delivered for free
Long distance calls can be routed to local termination point
and delivered as local calls
PRI and SIP Trunk Charge Comparison
Customer’s Before and After Comparison

Understanding access fees
SIP Trunk Access Fees
– SIP Trunk monthly access fee for customer
is $34/Mo.
– No other charges as that fee eliminates
local and long distance charges
– SIP Trunks sold in units of one
PRI Access Fees
– Range from $35 to $52/month and that fee
does not include local or long distance
charges
– Most PRIs are significantly under-utilized
since they are generally sold in bundles of
23 usable channels
– Recent sampling of customers showed on
average their PRI connections running at
40% capacity
– Effective unit cost 40% utilized PRI
interface is $87
– This means every PRI converted to a SIP
trunk will save $53/mo.

Understanding access fees
PRI under-utilization adds up
– Customer A has 92K PRI concurrent call capacity but only needs
27.6K
– Customer B has 57.5K PRI concurrent call capacity but only
needs 28.7K
– Customer C has 11.5K PRI concurrent call capacity but only
needs 2.8K
– Annual savings in all cases is substantial
PRI utilization data from three different size customers

Reduced toll charges
SIP trunks bring added cost
savings
Move from PRI to SIP trunks
reduces long distance and
local toll charges
Customer toll charge
reductions are almost half of
their total savings

What is needed to calculate SIP trunking ROI?
Information about customer
environment
–

–
–
Number of PRIs at site
Utilization rate of PRIs at site
Cost or PRIs
Number of concurrent calls at
site (from your call detail
records)
– The local outbound minutes
per site
– The outbound long distance
minutes per site
Information from SIP trunking
provider
– Cost per SIP trunk
– What else is included with the
