Simplex 4004/4005 DACT question

Post by slice1900 »

At my business I have a Simplex 4004 panel with a 4005 DACT installed and two phone lines. To make a long story short I'm looking to replace one of the phone lines with an LTE router that is VoLTE capable. Since the DACT is using 4+2 signaling it will work quite well with VoLTE but there may be a problem. No LTE routers available to me handle pulse dialing - does anyone know if the 4005 DACT uses pulse dialing only or is it configurable between pulse and DTMF dialing?

I looked online for the programming manual for the DACT but wasn't able to find anything so I wasn't able to find the answer myself. If it is using or is capable of using tone dialing then I should be good to go.

BTW yes I do realize there are dedicated cellular and internet dialers available, but I don't have any reason to go to a single system (i.e. cellular or internet only) since I will keep the other phone line. Having one dialup and one cellular will be more reliable than two dialup (which are both POTS only to the fiber panel on the side of the building now so I no longer have true redundancy like before when it was true POTS). I can also use the cellular as a backup for credit card processing in case the internet goes down so it will do double duty.
