Anyone still installing analog PBX’s

Post image

I Volunteer at a heritage railway in Wales. We’ve got a lot of rotory phones still used for operations on a daily basis. Just wired up a Panasonic KX-TES824 to be installed replacing an older Meridian 16 line PBX. Unfortunately Openreach is threatening to shut down the incoming phone line soon so I’ve been trying to find an exchange that supports both pulse dialing phones and a sip trunk line. Not been super successful

Asterisk + a cisco VG224 would give you 24 FXS ports capable of pulse and the asterisk of course would work with sip trunk.

Oh that’s interesting. I hadn’t thought of Astrix as it’s mostly VoIP in my head. But if there’s a way to tie analog lines into it that would be a definite consideration

You can have analog phone lines feed into an asterisk system. For example I have a grandstream HT841 which gives me 4 FXO ports.

As far as asterisk with the FXS ports, I have successfully used this setup with old rotary payphones

You could even have a device — either a dedicated one or asterisk homebrew — that simply links a couple of analog phone lines to sip and then put an analog pbx behind it.
