Hello, IMC does not implement any rfc, is kind of custom implementation for a instant messaging conferencing room, inspired from IRC, with /command-like control. From IETF, I think that only MSRP has specs about group chatting, nothing that is defined for MESSAGE requests. Anyhow, makes sense to propagate the content type, the IMC did not get proper attention for long time, no much interest around. It defaulted to text/plain because of the control commands. But it can be updated to propagate content type, the module is open for contributions/enhancements.

Probably worth to check also what the RFCs say in this regard, but in all cases if could be extended if its configurable for example by a module parameter.

I think the right behavior is to take the content-type header from the original message and use it in the messages imc sends. Is there a workaround that might help me achieve that? __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussionssr-users(a)lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
