SIP vs VoIP: What’s The Difference?
Although SIP and VoIP are often used interchangeably, they serve different purposes. SIP (Session Initiation Protocol) is a communication protocol that enables VoIP (Voice over Internet Protocol) by setting up the connections between devices.
VoIP refers to the technology that allows voice calls over the internet. SIP is more versatile as it can handle not just voice, but also video, messaging, and file sharing.
: SIP Trunking vs. VoIP.How to Choose the Right SIP Trunk Provider?
Choosing the right SIP trunk provider involves several factors:
- Look for a free porting service and a free trial period to gauge if it matches your business needs.
- Select a Tier-1 provider that has control over their network, as they are quick in solving issues due to fewer contacting processes involved.
- Identify the kind of technical customer support it offers, such as omnichannel support, support packages, and onboarding assistance. Is it just with higher plans, or is 24/7 support available for all customers?
- Find out the wait time for a support request or service outage.
- Explore the pricing plans and payment terms it offers–bundled pricing, pay-as-you-go, contract requirements, upscale and downscale opportunities.
- Carefully check the level of security they provide by looking at their third-party security certifications and network redundancy. It must offer security against hacks and malware.
- Find out if your existing hardware will blend in with the new SIP trunking or communications equipment.
- Determine the number of simultaneous calls your provider’s service can seamlessly handle.
- Gauge the communication channels your selected provider can support other than voice calling.
- Ensure that your chosen provider is operational in your area or your client’s area if you often need to make international phone calls or to sporadic locations.
Conclusion
In conclusion, SIP trunking solutions enhance multichannel communication, providing flexibility and a wealth of VoIP features beyond basic voice calls. Choosing the right SIP trunk provider requires careful consideration of features, reviews, and pricing.
