    help with 3cx relaiability

    I am Having a problem with the voice is not stable, so some calls one party is hearing, another call the other party is the one who hears, a third connection both parties are ok, I captured a log from a call that both parties couldn't hear each others even the connection is done sucsessfully

    I am talking about 2 external extensions 3cx Version3.1.2434.0 with static ip 209.124.188.150
    Stun is setup on both parties and the server to stun.3cx.com
    I am using HT-503 both ends, both of them are defined as external and are not bind to the media server ( it is a must because I don't have much bandwidth on my server) all ports has been opened as per the forum and the manual, I can do alot of sucsessfull calls. but my problem that it is not reliable ! I hope I can find some answers or guidance

    I am using G.723 does it make any problem?

    Another question is I see the calls RTPs been setup some times on high ports such as sip1:62332 to sip2:62222 even the HT-503 are locked on the 5004 or 5012 RTPs, I hope I can get more details on that
    Thanks,

    Unless you have extensions binded to media server using G723 codec is not a problem even thoug you receive that message on the logs, i, myself use G729 and i get all calls to go through without any problem.
    You can try thoug to bind both extensions to media server, use G711 codec and see if the problem still persists.

    Cheers

    I tried to bind to media server but no success!

    is there any guranteed solution for the NAT routers( I mean should I but a STUN server) or keep using the public STUNs?


    What does this mean? is it related to the g723?what codecs are supported by 3cxphonesystem?

    This sounds like a network configuration issue. Also note that its your VOIP provider that will determine sound quality. We dont support G723. Be sure to use a supported VOIP provider, and use G711. If you need G729, you can go for the commercial edition.
