CONDITIONS FOR INTEROPERABILITY TESTING networkWCS SIP/VOIP PRODUCTS AND SERVICES

  1. Production Test and Turn Up: Upon facilities deployment and/or Customer platform interconnection, WCS will provide engineering time for test & turn-up with expectation of similar engineering support from Customer. It should be the goal of both parties to see to an expeditious interconnection and subsequent test & turn-up
  1. Trial Deployment: Description of Customers intended use for trial (write description - SOW) Trial deployment is accomplished in the following ways:

 

IP interoperability accomplished by registering the customer’s gateway, softswitch (proxy) or session border controller (SBC) with WCS’s network.  This integration will require the customers engineering team to work directly with WCS’s engineering team and can be facilitated very rapidly.

PLEASE NOTE:

If the number is ported, WCS will dip a database and determine the actual carrier as well as LRN (location routing number). Billing for ported number would be rated at LRN’s NPANXX and not the dialed number.

 

OBJECTIVE

The objective of this document is to verify that a potential customer’s Voice over IP (VoIP) platform can properly interoperate with the WCS VoIP network via Session Initiation Protocol (SIP) and Real-Time Transport Protocol (RTP).

 

TESTING REQUIREMENTS

Customer is responsible for their softswitch provisioning.  

Customer must have the capability of providing SIP and RTP signaling captures for analysis in commonly used programs such as Ethereal or Wireshark. 

Communication will be primarily by e-mail using the following e-mail address: testing@wcs.com IM Communication is available upon request. WCS sales rep must be copied in all e-mail exchanges.

Upon test completion, customer could provide WCS with SIP traces of all test calls executed if requested.

 

TESTING SUPPORT

WCS will provide assistance in resolving any issues encountered during testing. Customer must send SIP and RTP traces to testing@wcs.com. File must contain only the call in question. 

 

TESTING COMPLETION

Customer must notify WCS via e-mail to testing@wcs.com  indicating that testing has been completed and must provide SIP call traces if requested.

WCS Engineering will review all customer applicable call traces to proceed with approval. 

Any outstanding issues encountered during test must be closed at this time.

WCS will notify customer of findings. WCS and Customer can proceed with further contractual negotiations as needed. 

 

TESTING NOTES 

Testing is restricted to 3 concurrent sessions. Customer is allowed to perform long call duration testing as long as this limit is not exceeded.  Any call attempts over 5 sessions will return 503 Temporarily Unavailable.
