[Freeswitch-users] gsmopen one-way voice issue

[Jeff Chua]

I'm configured freeswitch with gsmopen but can't seem to figure where
why I only get voice out from SIP-client to mobile-phone but not voice
from mobile to SIP client.

When I tried to call from mobile-phone to IVR extension 5000 and press
2 for the standard echo test (9196), I could hear the echo back. When
I tried to call 9195 for the five second delay echo test, I couldn't
anything.

I've add these settings in vars.xml as well.

  <X-PRE-PROCESS cmd="set" data="media_mix_inbound_outbound_codecs=true"/>
  <X-PRE-PROCESS cmd="set" data="inbound-late-negotiation=false"/>
  <X-PRE-PROCESS cmd="set" data="inbound-zrtp-passthru=false"/>
  <X-PRE-PROCESS cmd="set" data="disable-transcoding=false"/>
  <X-PRE-PROCESS cmd="set" data="inherit_codec=false"/>
  <X-PRE-PROCESS cmd="set" data="bypass_media=false"/>
  <X-PRE-PROCESS cmd="set" data="proxy_media=false"/>

What am I missing?

Thanks,
Jeff
