    I just tested the new version 16.9.0.rc1 and promptly got an error
    with
    this patch. With Deutsche Telekom, you always get a SRV record set. On
    the other hand, you mostly have to register 3 numbers - each must be
    registered on its own - to the same destination. Therefore, on
    startup,
    there are 3 registers done to the same destination. Often, one of the
    three numbers fails to register on the first attempt and therefore, it
    is done twice.

    With this patch, you're now using the second of usually 3 SRV entries
    and registration is done successfully (which would have worked too, if
    you would have used the first entry again, because it's just a very
    temporary problem) - but all succeeding calls (outgoing INVITEs)
    are now
    rejected (403 Forbidden), because they are going to the first entry of
    the SRV record set - which fails on Deutsche Telekom, because they
    await
    all subsequent actions to be done at the same server as the
    registration
    was done.


Out of interest: What product of theirs do you use? Is it companyflex?
I'm asking because I need to interface with Deutsche Telekom as well.

Best regards,
Andreas
