Hello list, I'm currently testing file transfer within the same SIP domain and the situation has just got odd! When I send a PDF or MP3 file, Freeswitch allows its transfer (meaning SIP Traffic is okay: INVITE, 180 Ringing, 200 OK, SEND Transaction, BYE, 200 OK) But when I try to send JPEG files, Freeswitch answers to the INVITE message with 415 Unsupported Media Type...so there is no SEND transaction! The fact is that I've checked the supported media types list in the config file 'mime.types' and I positively found the line: 'image/jpeg jpeg jpg jpe' There seems to be something wrong in FS, and well actually I don't know how to get rid of this Freeswitch's negative reply... Could you help me validating such transfer please? Thanks in advance David N.
