Hello,
just remembered about this one ...
hmm, I would say now that the right method would be AUTH, not MSRP, but
as you pointed, in SIP and HTTP the method is the first token in
request. I guess you had no chance to test with some client or look at
specs to see if they clarify somehow.
In both cases, the method seems to be static anyhow, either AUTH or MSRP
(iirc, the authentication is done only for AUTH). Both have the same
length, so a quick hack would be to replace internally MSRP with AUTH
for this case. But probably the safest is to extend the auth api with a
function that takes the method as parameter, which is eventually used
from inside msrp module.
Probably before the next release I will put some efforts in this module,
as the interest on it seems to increase, one of the goals being to add
an internal hash table to track the connections - it should bring some
performance improvement versus using htable in config...
Cheers,
Daniel

Hi,
MSRP AUTH requests must be authenticated using HTTP Digest
authentication. Part of the concatenated data when doing this
authentication is the method name. Because of the way MSRP requests
are formatted, the part of the request-line that would contain the
method name in HTTP or SIP requests is always MSRP. The MSRP method
name (AUTH in this case) is at the end of the request-line. When
Kamailio converts an MSRP request to SIP it has a method name of MSRP.
This means that when Kamailio authenticates an MSRP request it uses
"MSRP" as the method name, not the actual MSRP method name (AUTH).
Is this correct?
Should MSRP requests be authenticated with a method name of "MSRP"
(which kind-of makes sense as this is the string at the start of the
MSRP request line - which is where the method names are in HTTP and
SIP) or should the MSRP method name of "AUTH" be used?
If it is the later, does anyone know of an easy way to add this to
Kamailio?
Regards,
Peter
