July 24, 20241 yr Hi, I was looking to purchase 8x Menvier SD3 Speech Dialler. I can see this is now obsolete and the replacement is Eaton Universal 4G speech dialler. Our design is based around a PSTN version and we utilise our own PABX system so the BT PSTN switchoff will not be a problem for us. Do you have an alternative that supports a telephone line connection? Regards, Rubel
July 24, 20241 yr The sd1 is a pstn based dialler. Menvier SD1+ Speech Dialler [SD1-UK] The sd3 is obsolete and was a gsm based unit. Yes the SD3 replacement is the Eaton Universal 4G speech dialler [SD-LTE]
