None

I have a yeastar s100 configured with a peer trunk. Both incoming and outgoing are working okay. The only problem is there is no sound on both ends. Any ideas why?

Yes, plenty of ideas, but not knowing anything about how setup, what service you are using -SIP, analog, or GSM and if there is a router involved and if you are port forwarding, if SIP ALG is disabled, etc., the list of ideas is too long to go thru.

This is like saying, I have a headache, why?

Sorry Larry for the left out info. Its a SIP trunk (Point to point). My internet ISP is still the one who has provided me with the SIP Trunk so its configured on the ISP's router then to my PABX. From the router, if i use a sip software on my laptop, everything is working okay. But on the PABX that's where the issue is.

How is the NAT section in the PBX set? Did you add the local subnet? Is the IP for the SIP trunk local as well and is it added?

Hi Larry.

The NAT is set to STUN and the local subnet added. The SIP IP is provided by the ISP. Where exactly are you asking whether it's added? Its the one i have used to register the Trunk with.

Just an update. The issue was resolved by creating a static route for the IP provided by the ISP.
