[OpenSIPS-Users] can several SIP phones with same SIP account ring together and hang up asynchronous

[Robert Dyck]

This is a Linphone problem. A simple UA has no way of knowing that all the 
other UAs are unable to take the call. The Linphone developers should be 
encouraged to change the default response to a rejected call. Perhaps a 
universal reject could be an option but not the default.
