No Ringing/Music during transfer RRS feed

  • Question

  • Hello - 

    I'm finding that with Lync 2010, that callers hear silence when being transferred.  Seems to be universal, whether it's a user-to-user transfer or Exchange UM Auto-attendant transfer to a user.  

    Is this by design, and more importantly, does anyone know if it can be changed?  I've had a number of complaints of hang-ups, because the caller being transferred thought they were hung up on.

  • Any difference between internal or external calls? On external calls some gateways support music-on-hold during transfer.

  • I have been looking for an answer to this as well.  Any transfer, internal or external, gives only silence to the caller.  We have music on hold configured on all our Lync clients but that does not seem to make any difference when calls are transferred.  I would think there would be a solution to this question, but I cannot locate one.

  • Note that there's a difference between call parking, setting a call on hold, and call transfer.

    See this link for fixing the MoH when putting a call on hold:

  • For internal transfers you can use the link of Donlassini , if this happens for a response group check you're file format.

    Supported Wave File Formats

    All wave files must meet the following requirements:

    • 8-bit or 16-bit file
    • Linear pulse code modulation (LPCM), A-Law, or mu-Law format
    • Mono or stereo
    • 4MB or less

    For the best performance of wave files, a 16 kHz, mono, 16-bit Wave file is recommended.

  • For Aries Phones you can only use a Media Gateway to support MoH from the TDM but not lync internal.

    On Lync clients you can aktivate the MoH bei inband Client policy, default it is diabled.

    Be sure you use the format like K.smink wrote in this post.
