Hi Herning,
I didn't found any parameter related to SIP preconditions in that module.
But checking in the Kamailio, in the code we can see that there are some
sentences trying to check "sip precondition" in the module xcap_server.c.
How can we ignore it ?

Hello,
Kamailio does not handle media on its own (besides rtpengine and other
services).
If you want to modify the SDP inside your processed SIP messages, the
“sdpops” module is one good option.
Cheers,
Henning

Hi Team,
According with the RFC3312 (https://datatracker.ietf.org/doc/html/rfc3312)
The SDP parameters are the following
We define the following media level SDP attributes:
current-status = "a=curr:" precondition-type
SP status-type SP direction-tag
desired-status = "a=des:" precondition-type
SP strength-tag SP status-type
SP direction-tag
confirm-status = "a=conf:" precondition-type
SP status-type SP direction-tag
**precondition-type = "qos" | token
strength-tag = ("mandatory" | "optional" | "none"
= | "failure" | "unknown")**
status-type = ("e2e" | "local" | "remote")
direction-tag = ("none" | "send" | "recv" |
"sendrecv")
Which one should be the equivalent in the Kamailio?, is the a specific
module?
