Hello Theodor,
first of all you would need to have the configuration of Capro to follow the
scenario. And I guess you will not get your hands on that ;-)
But regarding your problem: please ask Cisco to fix your brand new phone!
According to the standards (RFC3261) the CANCEL message has to look exactly as
the original INVITE (e.g. To, From, request URI, etc.) so that the proxies
are able to route the CANCEL exactly the same way as the original INVITE. But
your phone uses the first few bytes of the topmost Record-Route header. This
complete bull****.
Sorry
Nils

Hello,
the VoIP Provider Carpo (www.carpo.com) uses Sip
EXpress router (0.10.99-iptelorg/tekelec-SOPv2
(i386/linux)).
When using the CP-7912G with this server, the CANCEL
reuqests aren't processed.
When testing myself, has the openser (it was easier to
set up with deb-packages) the same behaviour like the
SER?
Following a log from the Cisco CP-7912G with the 4
CANCEL that SER doesn't recognize.
Is it due to configuration or aren't the SIP-Messages
from 7912g not right?
This log was recorded without the CP-7912G ConnectMode
Parameter set to 0×00400000 (set bit 22 to use the
received ip address for NAT)
Before the 2 INVITE:
