I recently deployed ZRTP on the FreeSWITCH PBX on a Linux machine and I have two X-Lite softphones (on Windows) properly connected and secure with zfone and I am wondering why the FreeSWITCH log is returning the following errors. Also, the zfone on the machine receiving calls won't stay secure for a longtime after the two softphones are connected. I need help to understand this.
