How to check if the softphone is disconnected

[Sam]

Hi. We faced the following issue.
The softphone disconnects form the server in certain circumstances, e.g.:
1. failed to reach the given number
2. the call was hang up
3. the wi-fi is broken or the internet connection dropped

After that the client stays out of reach. Please tell, if there's a way to check (once per hour or else) the softphone has disconnected? Out developers say the softphone should understnad if it's disconnected or not after 5-10 minutes.

1. failed to reach the given number
2. the call was hang up

If connection fails when the call hangs up or the call didn't finish, this is likely a bug. We need clinet's and server's logs to understand what was wrong exactly.

3. the wi-fi is broken or the internet connection dropped

If the connection is temporarily dropped, there should be no disconnection, as the RTMFP/UDP protocol that doesn't use a traditional TCP connection to the server. In this case we're talking about WCS2 (powered by RTMFP), not WCS3 (Websocket+WebRTC).

After that the client stays out of reach. Please tell, if there's a way to check (once per hour or else) the softphone has disconnected? Out developers say the softphone should understnad if it's disconnected or not after 5-10 minutes.

In WCS2 and WCS3 there's a "keepalive' option you can configure in the server.properties config.
Example:

#The number of keep alive attempts before the connection is abandoned
keep_alive_max_attempts = 5

#Client should send keepalives every 5 seconds
keep_alive_peer=5000

#Server should send keepalives every 10 seconds
keep_alive_server=10000

With these settings, if you plug off the internet cable of the Flash client, the server makes 5 more unsuccessful attempts every 10 seconds, and after 50 seconds in total ends the connection and initiates unregistration on the SIP server.
