    Re: Transfer esternal calls - Cannot build transfer target b

    Bind your GXW-4104 to PBX in the Gateway/Providers menu. If you don't, your transfers will fail and your voice quality will suck. I had this same issue.

    Incidentally, voice quality with these things still sucks after you tie them to the PBX, but has provided us the impetus to go to a complete VOIP solution.

    Is this what your talking about:
    "PBX delivers audio " if not then how do you bind it ?

    In the Gateway / Providers menu it is indeed "PBX delivers Audio"

    In the Edit Extension menu it is "Bind to Media Server"

    I am not a fan of using these options for internal extensions since I believe they result sometimes in new issues. I did not read the full context of this thread though so if its for testing, go for it.

    Hector,

    I had a similar issue with my PSTN calls not transferring when doing an attended transfer.

    See my thread on this topic: http://www.3cx.com/forums/categorie...ing-a-pstn-call-fails-attended-transfer-2594/

    My equipment:
    GS GXW-4104 FXO gateway
    GS BT200 handsets

    The resolution for me was to set the following configurations:
    • 3CX -> Lines -> Manage -> PSTN Gateway
      -> Gateway Capabilities
      Supports Re-Invite = ON
      Supports Replaces header = OFF

      -> Other options
      PBX delivers audio = OFF
      Caller-Id in = 'Contact'
    (this setting for Caller-ID sends the 3CX virtual extension to the handsets instead of the calling number, so I can use the distinctive ring pattern of the BT200 - you may not want to change this from 'From' if you are using Caller-ID. I'm in the UK and the Caller-ID is not being transferred)

    Then for the PSTN Virtual Extensions:

    • 3CX -> Lines -> Manage -> Identification
      -> 10000 (same for 10001 and 10002)
      -> Other Options
      Maximum simultaneous calls = 3
    Then for each extension:
    • 3CX -> Extensions -> (select each one in turn)
      -> Other Options
      Supports Re-Invite = ON
      Supports Replaces header = ON
      SIP ID = (the extension number)
    Once all these were set, I was able to perform an attended transfer as well as blind transfer on both internal (SIP) calls and incoming PSTN calls.

    Hope that helps!

    Alec
