SIP Trunking FAQs

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.
