Why demand for SIP trunking is on the rise?

SIP trunking is a VoIP service based on the SIP protocol by which Internet telephony service providers (ITSPs) deliver telephony and unified communication services to customers. SIP trunking uses the power of the Internet to route calls onto the global Internet as well as localized networks until it reaches its destination (also known as IP-PBX). Whereas the traditional PBX system can route landline calls into its own localized network.

Advantages of SIP Trunking?

In order to achieve the true potential of digital VoIP-based phone systems, SIP trunking will be the key.

Traditional PBX gave businesses the advantage to use a single landline connection to be digitally split into many different lines within a building or department. Now, IP-PBX that is powered through SIP trunking goes one step further by linking up users across different cities and time zones by making voice independent from its traditional network so that users can call a desk phone, cell phone, or another number where ever that is located until it reaches a recipient.

The main benefit of IP telephony for organizations is to decrease operational cost and gain better call quality. Many small and medium-sized businesses (SMBs) are loving the scalability features of VoIP systems. These VoIP systems make it very easy for organizations to add new extensions and then configuring them with a softphone.

Why demand is increasing?

VoIP (and SIP trunking) is changing business processes of serving customers, offering technical support, selling products, and administrating service models. Here, we will list the reasons why there is high demand for SIP trunking.

  1. With the increase in the use of VoIP services by companies of all sizes, large deployments of SIP trunking with higher numbers of channels are on the rise. Typically, VoIP based on SIP trunk deployment of concurrent channels (sessions) in the range of 50 to 1000 addressing the need of medium to large-sized businesses. Whereas, small organizations can fulfill their needs with 10 to 50 concurrent channels.
  2. Call centers are also deploying SIP trunking to lower costs and to provide remote call agents. The cost difference between traditional telephony and VoIP is huge. With SIP trunking, call centers can also provide WebRTC based services such as click-to-talk, video calls, and instant messaging.
  3. Cloud-based hosted SIP trunking deployments are also increasing. Cloud-based services can provide customers the flexibility of serving a continental or global area with low startup and maintenance costs.
  4. SIP trunking and WebRTC will also support each other. The increase in the use of WebRTC will ultimately grow the SIP trunking business. High-volume calls and data generated through WebRTC will interest SIP trunking.
