What should I do for listen in two ways?

Are there any NAT or firewall between the PBX and the Cell Gateway?

no exist none device between these

Does the one-way audio issue happen even if you make a call between two extensions without through Cell Gateway?

Hi jpalacio,


Did you set "RTP relay =ON"?

If not, please try it again with "RTP relay = on".

You can change it [PBX]>[Options]>[Settings]>RTP relay

Thank you.
