It has been several days since I tried to run a gds370 (firmware 220.127.116.11) with a 2N indoor talk (firmware 18.104.22.168.5). The voice communication goes through without any problem but not the door opening dtmf code which works on telephones like the Yealink w52p, a ubiquiti telephone or grandstream 2130. The dtmf is configured in the same way in rfc on both devices.
Has anyone ever managed to get the 2n box to work with a gds3710? Because I can’t find the solution.
