I try to register an Android smartphone using data through 4G. My Asterisk 18.1.1 server is behind a NAT (Everything is ok within a LAN configuration).
I tried some configuration options with,
It doesn’t work till now. I can answer only the incoming call, but without any sound.
So I decided to try the IAX protocol, defining my phone through iax.conf
type = friend
It appears that I can not register my phone this way (IAX vs. SIP).
Now the point is to find a client who could support this IAX protocol for a Android.
I tried Mizudroid but it seems not be compatible with IAX
I tried Zoiper but my free version is not compatible, it’s only for SIP
Any idea for another app ?
Or maybe could it be possible to find another “simple” solution i.e. without STUN, VPN, etc. ?
