There are two standards based options for MSRP. Peer-to-peer between
clients (RFC 4975) with no servers involved and traffic between clients
relayed through a server (RFC 4976). RFC 4976 is used for NAT traversal and
policy (security/logging/etc) enforcement. The relay option requires the
MSRP client to support additional MSRP request types, procedures, and SDP
elements - essentially use of a relay requires the client to support this
and be configured for it.
There is a third option which is not standards based, that is B2BUA'ing
MSRP where a server pretends to be a pair of clients back-to-back. This is
what a lot of SBCs do.
As a server that is not a B2BUA Kamailio supports MSRP relay as per RFC
4976. However, your MSRP client needs to support RFC 4976 (and be
correctly configured) to make use of the relay.

Hi,****
** **
Is it possible to make MSRP to pass through kamailio instead of peer to
peer?****
** **
For me, my sip client registers with kamailio without any problem and able
to chat with other sip client as well. ****
But the chat communication using MSRP is always peer to peer, because of
the SDP negotiation. But I need make the msrp messages to pass through the
kamailio server.****
Please help me in configuring the kamailio.****
