As a final note, lets talk about why a client would be interested in on premise systems. Although the up front cost is a consideration for a client, in the long run they save money and gain flexibility. There are many reasons for premise based VoIP solutions, but here are five main reasons in my opinion:
- Any of the features they would like to implement in their environment do not cost extra, they're already included in the PBXact modules licensing. (Granted these are 25 year licenses, but that should be adequate for most businesses.)
- Any internal extension to extension calling is free because it does not traverse the SIP trunk provider, it's SIP endpoint to SIP endpoint. (This includes VPN remote workers, more on this in a later post)
- The ability to tie multiple locations together for free via IAX trunking.
- The monthly cost (minus the upfront PBX cost) is usually cheaper than using a SaaS solution like RingCentral. (Caveat - PaaS or IaaS sometimes can be comparable if there is a team that can deploy maintain the system, but the monthly cost of renting the hardware and paying the team could equal just purchasing the hardware outright over a span of a couple years. YMMV)
- Flexibility for very specific configurations
Now that we have all that out of the way, let's start diving into the topics that are relevant.
More to come, thanks for reading!
