Hello For my school project I have to build an sip client which support mobility. It means that when network change is detected and there is a call, mobile client have to send an INVITE message with the same CallID and new IP address (and of course register to proxy). I would like to build this client using python with python pjsua API, if possible. Do you think it is? Do you have any ideas how to achieve it? Thank you Otonag
