Are there options for managing the SIP client over the network?

Question

SIP

There was a need to organize a call to customers with the initiation of a call from 1c 7.7, and even spinning on the terminal server. I really don’t want to drag SIP, which means forwarding sound from clients to the server, so I really want to leave 1s in the terminal and run some SIPphone on client sites and then somehow (actually how ???) send it the command "call <number>" that's just popular sip clients did not find the ability to manage them, or perhaps out of ignorance I was looking for the wrong thing.
In general, is such a scheme realizable on the side of the sip client? Maybe someone will be able to tell SIPofon where there is some option to control it over the network?

Answer 1

Typically, this task is implemented on the side of the SIP server. For example, in Asterisk you can do it through call-files or the Originate command in AMI. The server itself will call the employee, and when he picks up the phone, the server will start calling the client.
