Hmmm - this looks suspicious :-) . An automatic re-registration could mean that CSipSimple automatically restarts. I know of another VoIP client that performs an auto-restart in case it crashes. Such a restart happens quite fast and is often barely noticeable. I cannot reproduce the problem here, thus can you check/see if CSipSimple just crashes and performs a automatic restart? If this is the case than we can try to get the Android logfies from the devices and analyse them.
