BVE - Paging - OTT

Hi there, we are currently an 'Over-the-Top' customer in one of our locations that has a warehouse with an existing amplifier and speaker system.

In recently years we replaced the analog phones in that location with the BVE Product. Since then, we have missed our over-head paging solution.

Upon investigation, I see the Algo 8180 does exactly what we want.

Looks like you add the SIP Server/Login/Password on the Algo to allow it to register and you're off to the races. This is a device we would purchase, install, and maintain ourselves.  This would require 2 x additional seats in our BVE product - 1 for the "ring after hours" and the other for the "page anytime".

In speaking to our rep - they indicate that this wont work in an OTT setup. "The VOIP platform will not authenticate an unknown device and it won’t work."

There is NO additional hardware or edge device installed in this location - the warehouse is in a non-COMCAST supported area.  They shipped us our phones, we plugged them in - and they worked. No firewall rules - no special configuration on our side. Assumingly they have a similar requirement (sip server, login, password) to function.

Does this sound right?  Any alternatives to our problem?

They suggested an ATA with an analog handoff - but isn't that configured the same way I'd want my Algo?
