    We recently setup a large call center using Hot Desk ACD Agrnts using SIP softphones (PC Client). The agents are required to do a screened transfer to other coworkers. As you all know this is a trans/conf feature of the MiVB. I have configured all parameters per Product support, which includes below:
    The consultation transfer does work on the Sip Softphone, however requires a few additional configuration steps as it is a Sip Conference.

    There are 3 locations we need to input the Conference FAC from the PBX, which will allow the Micollab Client to create a conference.
    First is on the Network Element for the PBX in User’s and Services It should be called Sip Conference FAC
    Second is in the Deployment Profile used to deploy these clients, it will be called Conference Access Code,
    Third will be the PBX Node in Micollab Client Services for that PBX, it will also be called Sip Conference FAC.
    Add the conference FAC from the PBX to these three locations, redeploy, and test again!

    And:
    However I think I may have forgot to mention a step, on the PBX we also need to have a Multicall key assigned to the sip softphone, which should allow it to use two lines for the conference.

    Here is where, i believe the issue lies. In order to configure an outgoing MC key you must program it as a virtual key. When the Agent attempts to perform the supervised transfer. the call is placed on hold and the other party is attempted to call, then the call fails and the original caller remains on hold.

    I configured a test SIP softphone, as a NON-ACD EXT with a multicall key of it’s own prime EXT and the trans.conf works perfectly.

    I have done a wire shark capture of the failure and here is what I find

    How are you creating the second line key for the ACD Agent, since and ACD agent ID can only be a single line appearance? Usually I’ll create a 2nd line derived from the agent ID (4*001 for Agent ID 4001, for example).

    Yes, same way, for example ACD AGENT 4001, the MC key is a single line key of **4001

    I seem to recall hearing/reading something somewhere that MiCollab client doesn’t like extensions that start with *, so maybe try a different number format?
