    I have 9 SPA504G phones. All of them can receive blind transfers except 1 from our Patten PSTN gateway. If any other phone does a blind transfer to this phone it fails with the following in the logs.
    Leg L:2418.4[Extn] is terminated: Cause: 406 Not Acceptable/INVITE from 192.168.XXX.XXX:5060
    L:2418.1[Line:XXXX<<anonymous] failed to reach Extn:XXXX, reason Not Acceptable HereReason Unknown

    The configs and firmware for all the phones appear to be the same. Any thoughts? Thanks in advance!

    Hi,

    can you please clarify what device is on ip address 192.168.XXX.XXX and sends the 406 message ?
    On the other tab of the extension on the Management Console and also on the Advanced settings of the gateway on the Management Console, options Replaces and Re-Invite are enabled ?
