We can dial out to most number just fine.
But when we try to dial any number with 678-336-XXXX we get an incompatible message.
This is the first time we've ever had this reported and the local number work fine if you call from another line not on our system (like your cell).
The 678-336-XXXX numbers are at another company unrelated to us and not on our system.
We have 1608-I and 6408D+ handsets mainly.
I've been working in the phone system a lot the past few days is it possible something got changed by mistake?
