Dom Cielo Posted June 21, 2014 Share Posted June 21, 2014 Hello to all. I installed a control panel that accepts commands via phone (DTMF), but since last week, she has had trouble accepting commands. When the connection is made by a conventional phone in just 50% of attempts to understand the central command. Already when performed by a mobile phone, with the phone company "A" with success in 75% of attempts, and another (B) in almost 100%. DTMF codes are generated by the device or the phone company? Anyway, the panel is under warranty, but I want to make sure that is a defect before changing. PS: sorry for my bad english. Quote Link to comment Share on other sites More sharing options...
james.wilson Posted June 22, 2014 Share Posted June 22, 2014 The tones are created by the device. Is it a long enough tone, some mobiles make a really short in time tone Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Dom Cielo Posted June 22, 2014 Author Share Posted June 22, 2014 Hello James. I tested with two different cell phones, and only when calls are made by the company "A" have success in all attempts. When using other, independent of the device, not always the panel understands the codes. Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted June 23, 2014 Share Posted June 23, 2014 So you have proved it's the device then? Quote Link to comment Share on other sites More sharing options...
Dom Cielo Posted June 23, 2014 Author Share Posted June 23, 2014 No. In fact it seems to me is the phone company, because regardless of the device used, the commands are only accepted when the line is the same phone company. Quote Link to comment Share on other sites More sharing options...
