I’m connecting Linphone with Asterisk 15.3 (PJSIP channel) and trying to configure also support
for the upload/download of files.
Practically Linphone Android uploads file to a PHP server and then sends a SIP MESSAGE towards
the other user to notify about a file to download.
The body of the MESSAGE is an XML containing URL that indicates from where the uploaded file should be downloaded.
When the destination user receives the MESSAGE with Content-Type:application/vnd.gsma.rcs-ft-http+xml
it should automatically start downloading the file.
Problem is that Asterisk responds with “415 Unsupported Media Type” to such kind of content type.
Is there any chance to let this content type to traverse Asterisk without being rejected?
