SIP Trunking – Transformation for Flexibility and Cost Savings

SIP Trunking – Transformation for Flexibility and Cost Savings


The traditional ISDN and TDM services are now passé as many organizations are switching to SIP trunking in order to avail its benefits like integrated capabilities, contact centre, and voice.
Instead of using multiple TDM lines, SIP trunking uses a data circuit to connect the corporate voice traffic to the network of the service provider. Cost savings is the primary reason why enterprises are fast migrating to SIP trunking. Experts have opined that PSTN costs can be cut down by almost 50 percent by analyzing the current spend and network configuration.

How SIP promotes flexibility and cost savings?

When you are using ISDN PRIs and TDM T1s, the voice circuits are provided in a package of multiple lines. As the owners of these lines, you end up paying for all these lines – actually you are paying for more than you need. However, if you switch to SIP, it facilitates the purchase of only the number of concurrent calls you require and on top of that you have the flexibility of buying additional lines when the volume of calls increase. SIP also helps to reduce the intra company call rates by transmitting the voice calls using the company’s data network. Thus, your organization can make substantial savings on the long distance intra-company calls.

Some of the other significant benefits of using SIP are:

  • Deeper insights into the call patterns
  • Better methods for disaster recovery
  • Hardware consolidation
  • Centralized management
  • Standardization of service providers
  • Is there any special preparation that your organization needs to make while switching to SIP trunking?

There are several things that organizations must undertake while migrating to the SIP trunking; this is mandatory especially when you are moving the communication from site-based distributed trunking.

As SIP is centralized, companies should prepare well for eventualities like delays in risk implementation, problems at the time of testing and turning up of SIP services.

Deployment issues that an organization can encounter are:

  • Organizations can lack in expertise when it comes to configuring or managing the voice platform like Contact Centers, PBXs and UC or Unified Communication solutions.
  • Not being aware of the ways to take complete advantage of new features.
  • Adequate technical knowledge when it comes to understanding complex SIP standards.
  • SBCs of session border control have been added to the network elements as they terminate SIP trunks while providing security, better call routing and numerous other critical functions.
  • Integration and interoperability is a huge issue because of different SIP vendors use different SIP methods during implementation.
  • Future of SIP in your organization

In order to successfully use and take advantage of SIP, you will need to analyze the impact of SIP on your data and voice environments. In order to achieve this, you will need to:

  • Analyze and find out the capability of the infrastructure at your office to support SIP services
  • Enhance the expertise in project management and related technical domain by building a pool of experts in your company or get into partnership with a competent advisor.
  • Find out the impact of SIP on the costs associated with delivery of communication services.
  • Build the solution architecture which includes SIP trunking and network services, and the remote sites (if possible).
  • Include the SIP trunking into your organizations existing operations and try to manage it for a long term.

It is best to start with a pilot project if you want to diminish risks associated with service disruption. You need to include integration, testing, functionality, interoperability and management ability so as to analyze the performance of the system. It is very important to plan the migration of your enterprise to SIP trunking.
