    Hi All,
    Can you please let me know what could be the possible reason for 3G to 2G Speech Handover Failure due to configuration Unsupported/Unacceptable.
    I have traced in ZTE and Huawei 3G/2G network in multiple handsets. I get problem in Sony Ericsson Xperia Ray, HTC Incredible S, Samsung I8150 etc But in Blackberry, ZTE Blade Android its successful. Failure is like
    UE->RNC UU_RRC_ULDCCH_Message handoverFromUTRANFailure.
    Could you please suggest me?
