1. A method for monitoring a common PBX phone line from a plurality of personal computer endpoints, comprising:
- registering for a single user multiple instances of application of a soft phone application respectively running on the plurality of personal computer endpoints, each instance being registered for a common PBX phone line under control of a Session Internet Protocol (SIP) server;
a first one of said multiple instances of application establishing a first SIP dialog with said SIP server;
a second one of said multiple instances of application establishing a second SIP dialog with said SIP server simultaneously with said first SIP dialog;
monitoring the status of the common PBX phone line simultaneously with said first instance of application and said second instance of application.

9. A method for monitoring and controlling a common PBX phone line controlled by an ECMA switching system with multiple instances of application of a SIP UA soft phone application hosted by a home server, comprising:
-
registering for a single user multiple instances of application of the SIP UA soft phone application on the home server, each instance being assigned a common phone line under control of the ECMA switching system;
sending out a SIP INVITE message to the ECMA switching system from a first one of the multiple instances of application requesting system status data;
on successful response, sending from the first one of the multiple instances of application one or more SIP INFO messages to get the status of the common phone line and to register for events with the ECMA switching system;
sending from the first one of the multiple instances of application subsequent commands as SIP INFO messages each with an ECMA command carried in the message body of the INFO message;
sending out a SIP INVITE message to the ECMA switching system from a second one of the multiple instances of application requesting system status data;
on successful response, sending from the second one of the multiple instances of application one or more SIP INFO messages to get the status of the common phone line and to register for events with the ECMA switching system simultaneously with said first instance of application;
sending from the second one of the multiple instances of application subsequent commands as SIP INFO messages each with an ECMA command carried in the message body of the INFO message. - View Dependent Claims (10, 11, 12, 13)

said first instance of application establishing a first SIP dialog with said PBX switching system server;
said second instance of application establishing a second SIP dialog with said PBX switching server;
monitoring the status of the common PBX phone line simultaneously with said first instance of application and said second instance of application. - View Dependent Claims (15, 16, 17, 18, 19, 20)
