Operator Delivery Models

For complete service delivery, operators need to provide their customers with:

  • Access Network
  • Termination Network

Depending on the nature of the service, one or both may not be needed.


Access Network

Access mechanisms consist of all ways used by the customers to reach the Application Servers realizing the service.


If the nature of the service requires an IP based client, then the Operators need to provide their customers with compatible devices like IP Phones, ATA Boxes or Softphones. In these cases no further access network is required and any customer who is online can use the services provided over Internet.


Examples of these services are consumer telephony, Enterprise PBX systems, Auto-Attendant and others.

Other services may need a telephony network to allow customers to dial-in to a specific published phone number.


Examples of such services are SIP Trunking, Unsubscribed VOIP, audio conferencing and others.


If an access network is needed for the service, operators may provide it themselves. They will need to have DID management systems in place that will forward PSTN phone numbers to SIP Trunks.


If operators want Media routes to arrange for Access, Media Routes can arrange its own telephony access network in most countries that can be used by operators for their services.


Further Access mechanisms include SMS/USSD driven access to services.

Most services that can be accessed through an IVR by dialing an access number may also be accessed via Short Messages or USSD short codes entered by customers on their mobile devices. The service application receives USSD short codes or SMS messages through a USSD gateway or SMPP (in case of SMS), and invokes pre-programmed service logic on each short code. Examples of such invoked services are:

  • Call-Back to the subscriber with voice Announcements
  • Call-back and connecting to a remote destination provided as part of the short code
  • Credit card payment
  • Balance checking
  • E-Banking through integration with third party online Banking systems through their exposed APIs
  • Database lookup and information retrieval
  • Third party application lookup and information retrieval e.g. weather, News etc.


Media Routes offers complete integration with third party applications, payment gateways and local databases. In case a USSD or SMPP gateway is supplied by the Operator, platform integrates with it, otherwise provides Dialogic Hardware as part of the installation/setup procedure and the cost of the hardware is added in the one-time setup charges.


A final access method is accessing services over the web via self-care portals and Enterprise or Operator web-sites. Examples of services invoked through this method include Web-based Call back, Click-to-Call, HTP based Service invocation by an external business application e.g. Enterprise CRM etc.

Termination Network

Some services will require termination of voice calls. For such services, the operator may  choose to provide its own termination network or can choose to use Media Routes own termination.


It is also possible to do a mix and match and offer some on-net or local destinations itself while Media Routes provides the rest of A-Z routes.


For all termination services, Media Routes provides CDRs in real-time or near real-time to the operator which it can process according to its own systems.


Another possibility is that the termination of calls is done on an all IP network without going to PSTN. Examples include On-Net calls for Consumer Telephony, ENUM based destination networks and domains etc. In all such cases, Media routes provides complete integration with terminating devices and networks realizing all IP based SIP call termination scenarios.
