    Hi Ping,<br>
    <br>
    My bad - in Call-ID and TO tag you have the B2B _entity_ ID, while
    you need the B2B _logic_ ID .....which is not part of the signaling
    at all .<br>
    <br>
    Now, in script, where do you need the b2b logic ID ? after creating
    the B2B session (after b2b_init() ) ? Or ?<br>
    <br>

                      It seems the function you mentioned is the

                      b2b_bridge_request(b2bl_key,entity_no)". <br>
                      <br>
                      Actually the function that I am trying to use is
                      the "b2b_bridge" (Exported MI Functions). It is
                      defined as below<br>
                      ----------------------------------<br>

                      1.5.2.  b2b_bridge<br>

                      Example: opensipsctl b2b_bridge 1020.30 <a

                      ----------------------------------<br>
                      <br>
                      In the example "1020.30" is the "dialog-id". This
                      is the parameter that I am not sure how to easily
                      access in the Opensips config. <br>
                      <br>
                      What I am trying to do is to get the value and
                      deliver to the next hop via a custom SIP header.
                      When the next hop tries to transfer the call to a
                      new destination. It can run the b2b_bridge command
                      straight away with the "dialog-id" without
                      rechieving the value from the Opensips database
                      (from b2b_logic or b2b_entities tables).

                              In script, in a b2b route, you can look at
                              the callid or TO tag (depending on the
                              direction) to get the key :<br>

                              <br>
                              The B2B uses that key as Call-ID when
                              acting as UAC and as To tag when acting as
                              UAS. You can run a SIP capture to see the
