Hello @movistardroip

I will try my best to answer since I need to use google translate to figure out what the issue is.

If you are changing internet providers then that means that your public IP is changing and your SIP trunk provider may not like that. That could also cause issues with port forwarding on the firewall if not set up correctly.
