Quote from: mdodds on April 24, 2015, 02:20:05 PMJust got a Grandstream HT-502 in to use on another system and decided to test it for pulse dial. No workee I wonder if I am missing a setting somewhere or if they have updated the firmware, or changed it internally and it doesn't work anymore.Anyone using one successfully?

Quote from: andy1702 on August 17, 2017, 03:49:05 AMI use a Grandstream 502 and it works with pulse dialling. The first thing I did when I got it was to turn off any firmware updates in the settings. I've had it about 18 months now. The only problem I had was that it didn't work with certain UK phones. It turns out the make/break ratio of the UK dials can fall just outside the range the Grandstream will allow. A quick tweak of the dial contacts cures this though.
