SIP Trunk Provider Evaluation 2019 by the Eastern Management Group

In this post I like to highlight a SIP Trunk Provider Evaluation by the Eastern Management Group. I came across a nice article regarding the evaluation of (some) SIP Trunk Providers which was carried out by the Eastern Management Group.

In this study 29 SIP Trunk Providers were evaluated based on a survey. More than 3.000 IT managers were asked. As far as I could read the focus resides primarily on SIP Trunk Providers in the US and such with global reach.

However, 29 SIP Trunk Providers are just a few. Depending on where you need a SIP Trunk you might need to research which are available at a certain world region, country and local area. As always on the market there are small and large SIP Trunk providers offering a different feature set for the SIP Trunk Services.

I recommend to take a closer look to what’s offered in detail and what SIP Trunk “architectures” are serviced, e.g. dedicated (physical) link vs. logical link (via existing Internet/MPLS connectivity), encrypted traffic support, clip no screening support, SBC support/compatibility (are there recommended SBCs/IP-PBX by the respective provider?), call authentication/authorization requirements…
