Installing a VOIP system in the office seemed like a good idea, but there were some subtleties that I had not counted on. Take the front door for instance. I should be easy to install an intercom that rings all the phone lines and allows someone to release the door and let the visitor in. Right? Wrong. There are very few SIP Door Phones on the market. I researched a number of models and it seemed like amateur hour. Poorly constructed, ugly, even models where the release was in the unit itself, such that anyone with a screwdriver could open the unit, short two wires and trigger the door to release.
Through my research I came across the Algo 8028. It did everything I needed, Attractive brushed steel, separate controller for security, simple browser based intercom to program it. So I buy it, install it, configure it with my Ring Central account (which goes really well) and, um, it rings but there is no voice. Hmm, call algo, upgrade the firmware (also easy) and voice is working but I cannot release the door.
Ok, another call to Algo, which tell me to call Ring Central, who tells me it is an Algo problem. Grrrr. So I email Algo a description of the problem, tell them what ring central said, and ask how to troubleshoot the issue. The next day I get an email that they spoke to Ring Central and determined that the issue was that the that Ring Central is converting SIP DTMF to RTP audio DTMF and the Algo 8028 will not recognize RTP audio DTMF. I appreciate the proactiveness.
Now hopefully either Algo will engineer a solution or Ring Central will change a setting and not convert the SIP DTMF. Until then, I can answer the door, but not open it.
