    Since there is no official support for ht488 i have to open this new topic:

    1st scenario:
    HT488 configured as extension 101 on fxs and also configured as extension 10001 on local PSTN line.
    Want to forward PSTN lines to another extension. This is done by setting in Basic Settings Number of rings to 0 and Forward to VOIP field to:
    - extension given by 3cx - there is no sound on one way.
    - local IP: port of the extension - everything works fine
    - ring group extension where the extension i want to forward the call to is included - everything works fine.
    Any setting i should make in order to be able to forward incoming pstn call directly to 3cx extension (and not to ip:port of extension or ringgroup)?

    2nd scenario:

    Internal extensions:
    100 (3cx voip client, configured on the server with 3cx -
    101 - fxs port of ht488 -

    router- internal - external xxx.xxx.xxx.xxx - model: trendnet tew-4528brp.

    external extension
    111 - fxs port of ht488 with public ip address yyy.yyy.yyy.yyy

    Calls from 111 to 100 or 101 work without any problem (this issue has been solved somehow since 2 weeks ago i couldn't do it)
    Calls from 100 or 101 to 111 do not work (almost) at all: phone connected to external 488 rings but there is no voice.
    3cx server log:

    Firewall test result:
    1 9000 Warning (8) Local port is not blocked from outside. STUN server has returned global port different from the local one, but the local port is also accessible from outside.
    2 9000 Warning (10) Port is open, but port number has been changed. In many cases, this will present a problem and cause one way audio or no inbound calls. See this FAQ: http://www.3cx.com/support/firewal-checker.html
    externalAddress =

    this is for all ports from 9000 to 9015.

    Any ideas how to solve these issues? Thx.
