Q
MV-374/MV-378: One way Audio (version 2 : 1 IP 4/8 ports)
 

If IPPBX/Asterisk is in internal network, you must build stun server in any pc that in the same network 
Otherwise, the voice will be one way.

We develop a stun server and dial peer server. (MV-374/378: ship after 3/23 already build in this server)
Download

Let me introduce dial peer server
Lan to mobile: Dial peer software will look for available channel to dial out.
Dial peer include stun server function and can manager several MV-37X at the same time.
E.g When the first port is busy, MV-378 will use the second port to dail out…and so forth.
Please read user manual
