When choosing the best SIP Trunk provider for your business, there a several factors to consider:
Network – Does the SIP Trunk provider run its own network, or is it rebranded from a larger partner? This can heavily affect the price you pay for calls and the level of support you will receive.
Competitive costs – How does your SIP Trunk provider stack off between cost and quality? Cheap SIP Trunk packages often limit the options to quickly scale up or down or offer the minimum level of support.
Support – What service level agreements (SLAs) does the provider offer? How long will you have to wait for serious issues to be dealt with and will these be fixed at any time of day?
Fraud protection – Does the provider offer the right protection? SIP providers can put spend and dialing limitations on their customer’s accounts so that even if there was a security breach, costs would be capped.
