Learn More About SIP Trunking Solutions

What are SIP Trunking Solutions?

SIP (Session Initiation Protocol) trunking enables the online transmission of communications of various forms, including voice. SIP trunking is often confused with web conferencing and VoIP tools, but the difference between the two is that SIP is often used in web conferencing and VoIP tools, which offer it along with other protocols and features. Businesses use SIP trunking to minimize communications costs and enable unlimited calling. SIP trunking also often includes support for dialing into meetings and offers equal audio quality to telephones, with a simpler implementation process.

SIP Trunking Features & Capabilities

SIP trunking providers offer slightly differing feature sets depending on the provider, but below are some of the essential features offered by most SIP trunking providers.

  • Communications transmission
  • Inbound and outbound calls
  • Support for telephony and web conferencing
  • High audio quality

SIP Trunking Solutions Comparison

When considering an SIP trunking solution, look at the following factors of each offering before making a purchasing decision.

  1. Phone vs internet support: Most SIP trunking providers offer some level of support for phone and internet calling, but if you have a specific need, such as a toll-free number, or unlimited web calls, you should ensure the provider you choose offers those features.
  2. Pay as you go vs subscription: Most SIP trunking providers charge a subscription for their services, or a pay as you go fee based on number of calls. Pay as you go is great for businesses where call volume fluctuates, but subscriptions tend to be cheaper for businesses with consistent call volumes.
  3. Telephony Needs: Some SIP trunking providers focus specifically on web communications. For businesses that already have a telephony solution they are happy with, these SIP trunking providers may be preferred.

SIP Trunking Providers Pricing Information

SIP trunking providers typically charge either as a monthly subscription that supports a certain number of calls, or with a pay as you go model where businesses p[ay based on how often they use the features provided by SIP trunking tool. Exact pricing is highly dependent on the provider, but businesses should expect to pay at least $0.008 per minute for most SIP trunking tools.

Frequently Asked Questions

Should I use an SIP trunking provider or a VoiP tool?

Whether you should go with an SIP trunking provider or a VoiP tool largely depends on your specific needs. If you need primarily web conferencing features, and also want access to features like meeting organization, a VoiP or web conferencing tool is ideal. If you want web conferencing and telephony features though, a SIP trunking provider may be preferred. Businesses can also use both.

If I already have telephony setup, is it worth it to switch to an SIP trunking provider?

If you already have a telephony setup you are happy with, SIP trunking can still be a cheap way to handle your web conferencing. In the long term, it is often also more affordable than many telephony solutions.

How is SIP trunking implemented?

Most SIP trunking providers offer implementation and support services as part of their packages. Notably, this implementation process can differ from offering to offering. Most often, it is a simple software installation on the network, or on individual workstations.
