Hello, having an issue with a set when dialing a local call 9+local, I can dial 9+1 and any number and it works fine, if I register a 9611 set on this port / number all works well. I have wiped ext, and all credentials of this and reprogrammed, still the same issue. I have other B179 sets out working fine, not sure what I am missing as this is related to this set only,,, any help would be appreciated.
