    I am having issues with my Snom 710 phone, I can't hear anything when I answer a call but the other party could hear me very well. I have call echo checks but same thing.

    Any help, what might be the problem.

    thank you

    Hello @network52

    Is this a local or remote extension? Also what firmware is the phone on and what template are you using?
    Is the issue present when you are calling another extension?

    Have you port forwarded the ports at the remote site? Each phone should have it's own sip an RTP port and they should be forwarded to the local IP of the phone at the remote site.

    Yes, did firewall check and results were okay without any issues.

    Have you tried enabling PBX delivers audio under the extension settings / rights? One way audio usually indicates a firewall issue. You could try installing an SBC as a test and try to provision the phone behind the SBC to eliminate any firewall issues at the remote site.

    It is the same issue even through an SBC? Have you tried a different handset?

    @network52,

    Please try/check next and test again:
    - Check in routers (local and remote) if SIP ALG is disabled
    - Reset phone to factory default
    - Try phone on the same LAN as the PBX reside

    Do you have issues only with this particular phone (Snom710) or with all the connected phones?
    Do the softphone(s) work correctly (e.g. Windows, iPhone, Android)?
