I have a newly installed Issabel, virtually no settings on it, when I make connections on the internal network everything works perfectly, even when I try to connect from an internal network extension to a branch in the cloud works.
But when I try to call from any extension on the internet to any other, the connection drops with exactly 32 seconds, the error I have in the CLI is: chan_sip.c ... Packet timed out after 32000ms with no response.
