I am trying to set up an SBC on a raspberry pi (Raspberry Pi 2 Model B, fresh installation with NOOBS 1.9.2 installer).
At first, I found errors in the log file, stating problems with the DNS server. I did some research and found this very helpful post. After enabling wait for network at boot, the DNS errors disappeared. However, now I get a new error, I have no Idea how to solve. It says: "Connection is terminated by peer".
On the server-side I am unable to to find any error. I double-checked my network settings and everything seems to be as it should (according to the admin manual). Also the Android-App (which to my knowledge should use the same ports) works flawless from the remote location, in which I am trying to set up the SBC. Probably this could be counted as proof that port forwarding and firewall is configured correctly. The event log in the 3CX management console does not show anything at all that is related to the SBC.
Here is the complete log from the SBC:
*Domain and IP changed for privacy reason.
