Hi Duane,

AFAIK, b2b can do transfer only for established calls - this is why you get that err message.

Here is a SIP Trace of my Call Pickup

If you do a search for *Replaces* you will see the INVITE that is sent in order to do a Call Pickup of the call coming in from the SIP Provider.

    In the past I used a VoIP SIP trunk provider that I guess used
    Asterisk
    servers as their gateways and I was able to perform the Call
    Pickup feature
    with OpenSIPS and the SIP Trunk Provider. Now I have a new
    provider and I
    need to use the B2B modules for Transfers.  Currently I am not able to
    perform Call Pickup with calls coming from the PSTN to internal
    customers.
    I tried to use the b2b_bridge_request but when the PSTN Caller calls
    internal_user_A and internal_user_B tries to do a call pickup I
    see the
    following error in syslog

     ERROR:b2b_logic:b2bl_bridge_msg: Wrong state for entity ek=
    [B2B.106.390],
    tk=[536.0]

    When I do an "opensipsctl fifo b2b_list" all the states are zero.

    So does the state of the call have to be a "on call" state instead
    of a
    "calling" state?  How can you bridge a call that is in process of
    ringing?
