Hi, I've been using Linphone on Android for many years as a secondary option, which I liked.
I successfully dial and receive calls. I am hoping to use Linphone on my Android as a primary option and, in testing, have run into a problem. My droid Linphone is connected to an Asterisk PBX. I just noticed DTMF does not seem to be working in some cases (as mentioned, I can dial-out). When I try to access voicemail the PBX doesn't seem to respond when I enter my mailbox number. When I noticed this my next test was to try DTMF on another service. I called a customer support number and tried to use DTMF. That didn't work, either. I do not hear the tones. Can anyone please offer some suggestions on how I can get this working? Thank you very much!
