UPDATE: The Springfield-Greene County 9-1-1 Emergency Communications Department has been notified by AT&T that the issue for the 736 exchange in the Strafford area has been resolved.
AT&T customers in the Strafford area haven't been able to call 911 from a landline Tuesday morning.
The Springfield-Greene County emergency communications director says this affects customers who have a 7-3-6 prefix.
Until the problem is fixed, you're asked to use a cell phone to dial 911.
The center says it was told earlier this situation was resolved, but it wasn't.
