The second content-type is invisible to opensips.
I don't think opensips knows about mime message/cpim.
Some functions, for instance handle_publish assume that the start of
the body is also the start of xml. With message/cpim that is not the case.
Here is the part of MESSAGE that is of interest.
Content-Encoding: deflate
Content-Type: message/cpim
Content-Length: 249
Priority: non-urgent
Expires: 0
User-Agent: Linphone-Desktop/6.2.0-beta.19+1d6910749 (silver.mylan)
fedora/44 Qt/6.9.1 LinphoneSDK/5.5.0-beta-84-g7a481f7e71
Message Body
From: <sip:[email protected]>\r\n
To: <sip:[email protected]>\r\n
DateTime: 2026-05-04T16:46:24Z\r\n
\r\n
Content-Type: application/im-iscomposing+xml\r\n
Content-Length: 207\r\n
\r\n
<?xml version="1.0" encoding="UTF-8" standalone="no" ?><isComposing
xmlns="urn:ietf:params:xml:ns:im-iscomposing"><state>active</state><contenttype>text/plain</contenttype><refresh>60</refresh></isComposing>
message/cpim enforces this format for the body.
