How to test if the connection with the server is active

[AlessandroMenchiniTmaxLab]

Hello everyone,

I apologize in advance, but I don't know the SIP protocol, although I managed to figure out a few things. Based on the 'SoftPhone' example, I was able to create code that intercepts an incoming call. I’d like to understand if there is a simple way to periodically check if the connection with the server is still active, as I would like to perform a new registration if necessary.

Thank you.

If you're referring to the SIP connection the only to check is to send a request and verify you get a response. SIP typically utilises UDP and as such there is no persistent connection at the network layer.

The SIP registration mechanism does already have a periodic re-register mechanism. You set the period by using the Expires header. For example if you set it to 180s then a new REGISTER request should be sent every 3 minutes.

Thank you, could you point me to an example of sending a message and receiving the corresponding response, if available in the provided examples?
