I’m using VitalPBX VitalPBX 2.0.5-5 and I can’t find the problem but DTMF is not working in our system. For example my extension is configured as DTMF AUTO but when I try to transfer a phone call I can’t use *2 because the DTMF is not detected. I’ve tried with DTMF configured with RFC2833 (that was how our old Elastix was configured and all was working fine) but also does not works.
Any hint? This happens with Cisco Phones, Alcatel, Grandstream…so I suppose that the problem is in some VitalPBX setting.
