    Hello all

    V6.1.0 (Windows 2003 Server)

    Call comes in via VoIPtalk line

    PSTN > VoIPtalk > DR > Ext > Voicemail

    If a call follows the above route, and a caller hangs up during voicemail without pressing #, the disconnection is not detected...if a call hangs up at any other point during the call, disconnection is detected without a problem

    I have tried this using the nat.voiptalk.org:5065 and also the natproxy.voiptalk.org

    any thoughts

    Hi

    If you capture such a call with Wireshark do you see the DTMF # signal coming inbound from Voiptalk to 3CX?

    Also, when the caller ends the call, there should be a BYE coming from VOIPtalk to 3CX. Do you see this in the capture?

    Hello

    I do not see the BYE packet from VoIPtalk when in the voicemail section of the call, the 3cx box eventually sends a BYE to VoIPtalk ending the call.

    However, during any other section of the call, VoIPtalk does send a BYE to the pbx

    I have also raised this with VoIPtalk

    Hi there

    Wireshark must be installed on the same machine as the 3CX PhoneSystem to ensure that all the relevant packets are captured.

    Regards

    Kevin

    Hi tomlinm (mark),

    I'm having a very similar issue to you see: http://www.3cx.com/forums/calls-routed-to-voicemail-remain-connected-9624.html

    I also use voiptalk as my SIP trunk provider and was wondering if you still have this problem or found a solution?

    Thanks,
    Ads.

    Sounds like your VoIP trunk provider is not acknowledging the hangup and issuing a BYE SIP message to deconstruct the SIP sessions(your call).

    Speak with your VIP provider.
