Just out of curiousity what version of phone software are
you running?
It is the POS3-07-1-00 (7.1) SIP Firmware, should be the latest one.

As you can see, the ACK for the 407 gets forwarded by SER.
It does not match
the previous transaction. This should not be the

there anything we
can do about this, except flying to munich and
beat on cisco?
Best regards,
Martin
