</span>I still can't fix the one-way gamopen audio issue on freeswitch. It's<br>
running the latest freeswitch git version.<br>
<br>
I'm using Huaweil USB modem. The modem works fine in with<br>
Asterisk/chan_dongle (audio works both ways).<br>
<br>
SIP phone calling from wifi -> to freeswitch -> to another SIP phone<br>
on the same wfil -> audio works both ways.<br>
<br>
SIP phone calling from wifl -> to freeswitch -> to gsmopen -> Mobile<br>
Phone ... -> one-way audio only from SIP phone. GSM to SIP no audio.<br>
