Not sure it is a bug or feature for outbound calls


For UCM6301. Firmware version

While battle inbound route, I upgrade the PBX to the last version.
Now, inbound calls working, but all outbound got rejected.

So, I whitelist all extensions, still no luck.
had to change privilege level from “national”(all extensions are at national level ) down to local. outbound back to working again.

Fun system to work with…


Check your SIP settings - domain --> should be IP / Host Name
