Sip Trunking Providers: How to Find them for Your Business

SIP Trunking refers to a technology that transmits your voice calls over the Internet rather than traditional phone lines. To improve communication capabilities and save money, many businesses are turning to SIP Trunking.

With so many SIP Trunk providers in the market, it can be a challenge to pick the right one. To make things easy for you, we have provided guidelines on how to find the right SIP Trunking service provider for your business.

Voice Quality

Voice quality is an important aspect of telecommunication, and the SIP Trunking service would fall flat in the absence of high-quality communications. While finding SIP Trunking services for your business, you need to look for a service provider who can ensure users can send and receive calls efficiently and clearly.

Look for Tier 1 carriers that have all comprehensive networks to deliver voice and data to their customers. Tier 1 carriers do not borrow network capacity from others. You should stay away for SIP Trunking services that use Least-cost routing, which compromises on voice quality to save on costs.

You need to look for a SIP Trunking service that has at least one PoP (point of presence) in the region you want to reach to ensure call clarity and low latency.

Coverage

The geographical coverage allows SIP Trunking service to expand VoIP infrastructure without any complexities, like negotiating with local carriers. The SIP Trunking service should be able to facilitate international calls.

The service provider should offer different numbers across countries to facilitate inbound calls. For example, it should provide a local UK number to its US client to facilitate communication with UK based customers. In that case, the UK customers would be calling a local UK number and don’t need to dial an international call to connect to the US office.

Cost

One of the reasons for using SIP Trunking is reducing communication costs.  Long distances calling, which includes international calls, are cheaper over SIP Trunks. A pay-as-you-go plan can help you keep the costs low as you only pay for the services you need.  This is better than upfront payment for channels where you might be paying for a bundle of services that you don’t need.

You can easily scale your VoIP system with SIP Trunking without additional investment in infrastructure. SIP Trunk providers offer different plans, and you need to select a plan that meets your business requirements and offers the best value for money.

Reliability

The reliability of communication is directly related to business continuity. If there are consistent call drops, you lose the benefits of switching to SIP Trunking.  You need to look for SIP Trunking services that have a redundant infrastructure to ensure a higher SLA guarantee.

A SIP Trunk service provider with multiple carrier connections across continents can ensure reliability in long-distance calling. Look for SIP Trunking services that offer 99.9% uptime guaranteed and are connected to multiple Tier 1 carriers in different continents where you want to reach.

Security

Security of communication is a big concern for businesses. The SIP Trunking service provider should protect your network and ensure your calls do not get intercepted. Look for service providers that offer IP authentication to protect your SIP Trunks.

Leading SIP Trunking service providers use Secure Real-time Transport Protocol (SRTP) and Transport Layer Security to encrypt Trunks.

Interoperability

Companies that have already invested in telephone systems need to look at SIP Trunking services that offer interoperability with existing telephone systems. This will ensure the company does not have to go through a complete system/technology overhaul. Leading SIP Trunk service providers offer interoperability through IP-PBXs and standard soft switches.

Flexibility

Flexibility is an important factor for businesses. Leading SIP Trunk service providers offer different levels of flexibility in the form of flexible contracts. In such a contract set up, the client can choose to increase or decrease services as per business needs. The SIP Trunk service is not locked down to undesirable terms and conditions.

Some of the flexibility features include configure softphone compatibility, add IP access control lists, adjust services, and change phone numbers. This allows businesses to scale up and down to meet peak and low business periods and control costs.

So how do you choose Sip truck providers?
