Description and Objective

Apeiron Voice Recurring Charged Services will be measured on the basis of cumulative service availability. Target values and performance metrics amongst these categories will be defined herein as well as measurement methodologies, exclusions, and description of Customer recourse.


The application of these measurements and metrics with regards to service measurements will be defined and applied on a Service Category basis.

Service Categories include in this SLA include:

  • Apeiron Voice Services billed via monthly recurring charges

Service Categories

Apeiron Voice MRC Services

Apeiron Voice MRC Services refer to voice services for which monthly recurring charges are applied. These include but are not limited to SIP Trunk channel charges (where applicable, for example flat rate and burstable inbound trunking USOCs), Direct Inward Dial numbers, Toll Free numbers, and associated features including but not limited to voicemail, conferencing, fax and CNAM delivery line items that are delivered from Apeiron to Customer and have recurring charges applied on a monthly invoice.


Service Availability

Apeiron voice services shall be available 99.99% of the time with traffic being delivered to/from the PSTN, Apeiron and customer locations measured over a calendar month.

The availability of the service shall be calculated at the end of each month in accordance with the following formula:

MA=((MM–EM-OM) / (MM-EM)) * 100


  • MA=Availability of the service for month
  • MM=Total minutes in month
  • EM=Excluded minutes in the month
  • OM=Outage minutes in the month

Service Unavailability is measured from the time services become unavailable from PSTN origination points to either the end user the Apeiron feature servers to the time service is again available to receive phone calls. Service unavailability is measured by the Apeiron NMS in response to trouble tickets opened by Customer.

If Apeiron fails to meet the above Voice Recurring Service availability SLA, the credit for each cumulative hour of Service Unavailability, exceeding the initial seven and two tenths (7.2) minutes of unavailability per month, shall be one (1) day’s credit pro-rated from Customer’s Recurring Monthly Service Fees for the impaired Internet Access Service, not to exceed a total of seven (7) day’s prorated recurring monthly service charges.

For example, the Customer would be eligible for credits as follows:

Cumulative Service Unavailability Customer Credit # Days
≤ 7.2 min. 0
> 7.2min. and ≤ 1 Hour 1
> 01 Hour and ≤ 2 Hours 2
> 02 Hours and ≤ 3 Hours 3
> 03 Hours and ≤ 7 Hours 5
> 7 Hours and ≤ 8 Hours 7

Exclusions: Credits will not be applied to customer account due to Service Unavailability resulting from (a) scheduled Network maintenance; (b) the occurrence of a Force Majeure event; (c) customer provided Internet service outages; (d) failure to route issues based on customer CPE programming which will not accept calls on secondary or tertiary routes attempted by Apeiron call processing; or (e) transmission errors across the portion of the Internet which is off-net to Apeiron.
