I still can't fix the one-way gamopen audio issue on freeswitch. It's
running the latest freeswitch git version.

I'm using Huaweil USB modem. The modem works fine in with
Asterisk/chan_dongle (audio works both ways).

SIP phone calling from wifi -> to freeswitch -> to another SIP phone
on the same wfil -> audio works both ways.

SIP phone calling from wifl -> to freeswitch -> to gsmopen -> Mobile
Phone ... -> one-way audio only from SIP phone. GSM to SIP no audio.


Thanks,
Jeff
