SIP Termination: Definition, Utility, And How To Choose A Provider Definition And Utility

Latest News

SIP is an abbreviation for Session Initiation Protocol – this is an application layer protocol that allows initiating, modifying or ending VoIP calls or other types of multimedia sessions. Given that Internet access is cheaper per volume of data transferred compared to traditional phone landlines or mobile phone networks and the cost stays the same regardless of geographic distance, it makes a lot of sense to businesses to use the Internet for calls and data exchange.

SIP trunking is the term that designates the manipulation of such calls and can be of two types: SIP origination (receiving inbound calls) and SIP termination (making outbound calls). These two processes are not interdependent and can be offered by different providers. Companies even tend to advertise these two types of services separately as can be witnessed on the website of the following VoIP termination service provider located at didlogic.com/voice/sip-trunks/sip-termination/ , as well as on many other similar sites.

Important Aspects To Consider When Looking For A SIP Termination Provider

            Among the features/ aspects that matter most are the following:

  • The quality and size of the physical network, in particular, the infrastructure owned by the provider or which can be directly accessed by the provider. This would allow efficient routing of media streams (e.g. keeping them within the country and avoiding loops), fast links to carriers, a good signal, and minimum latency regardless of geography. Traits to look for are the bandwidth, and size of the network (access to all continents should be normally possible with top providers), the density of carriers at each of the provider’s nodes, etc.
  • Being the owner of the infrastructure is another important aspect since resellers usually have less control of the network (e.g. the routing of the media streams) and their services tend to be more expensive.
  • Services offered by the provider should be easy to scale up or down dynamically at any moment, according to the necessities of the business. Thus, it should be possible to add or remove lines/channels on the go – top providers may allow this for free, so a business can take its time to adjust the service to its needs, without being penalized for this. Top providers can also typically offer capacities of thousands of live channels (adjustable) to individual companies.
  • Support for a number of trunking scenarios is also of paramount importance (two-way SIP trunking, VoIP transit via tier 1 or regional carriers, local DID numbers, etc.). Ideally, it should be possible to contract any given combination of services at any given volume.

SIP trunking services can normally help a business save between 60-80% of the money paid for a traditional phone system, hence, the motivation to adopt this technology is very powerful. Nevertheless, one should carefully consider the listed aspects and choose a provider according to them in order to benefit from the best services.
