Re: [Freeswitch-dev] how to encrypt the sip message?

If you are talking about the voip provider like ET263 in China, I would offer some suggestions. For sip part you need to modify libsofia to support customized encryption. For RTP packet, it is related to switch_rtp.c in Freeswitch. Actually, I have supported ET263 encryption in my modified version of FS. Hope this info is helpful to you.
