Dear
all
I might have noticed
a bug in SST module:
If I send an INVITE
with
Session-Expires:
300
Supported: timer
I get rejected with
422 Session-Timer too small.
If a Min-SE: x
header with x > set min_se parameter included I do not get the
message.
This is IMHO wrong
behavior, as Min-SE is optional in initial INVITE-requests sent by the phone
acc. RFC 4028, table 1.
Another thing that I
noticed is the response to this message includes the Min-SE header (as it
should), but has no linebreak after it (at least in kamailio branch 1.4). The
message looks like
MIN-SE:120Server:
Kamailio (1.4.1-notls (i386/linux))
The phone call
cannot be performed.
At least one thing
is IMHO wrong, as the phone cannot complete the call. It might be wrong the call
gets rejected, or the answer might be possible like this, but then the phone
cannot extract Min-SE due to wrong format.
Any opinions on this?
