GS WAVE connects but no audio


#1

I have set up the GS WAVE on our own cloud based server. It connects perfect.

Calls within our network connect perfect and audio very good.

However, if I call outside our network (a cell phone or landline) the call dials, but when the receiving party answers the audio cuts off. Neither I can hear nor the receiving party can hear.

It appears there is a codec or other setting I have missed/

Has anyone had this issue? Any suggestions where to look?

Thanks

Had more success with this when I used TCP instead of UDP signalling.

I’m having this issue as well I have tried GrandStream’s app and X-Lite

If I call my cell phone from the softphone outside the network it dials but no audio

Hi,

I Think you must configure or redirect in your router the RTP ports.

If you connect by a VPN is not necessray, but you access direct to router you have to redirect RTP ports

Hi,
Under “PBX Settings” -> “SIP Settings” --> “NAT” --> “External Host” make sure the entered IP address matches the Public IP address (or use any DDNS service).
Hope this helps. :slight_smile:
