    I use android client CSipSimple. This software has the feature of sending SIP text message.

    I also use a GOIP PSTN gateway device. This device has the feature of transforming a GSM SMS to a SIP text.

    So theoretically, CSipSimple should be able to talk with my GOIP and when people send SMS to my PSTN device I should be able to receive it on my SIP software phone CSipSimple;

    The problem is, when both GOIP device & CSipSimple are registered to 3CX, the SIP INVITE with MESSAGE method just not passed-by by 3CX server;

    Does anybody know how 3CX phone system handle SIP INVITE with MESSAGE method? blocked it? or just discard it?

    PBX does not accept malformed packets
    MESSAGE request with "Contact:" header is one of them
    Please contact GOIP gateway technical support.

    Thanks
