Our primary upstream carrier for inbound calling and inbound and outbound messaging on the PSTN is currently experiencing an attack on its network. Many if not most of the United States largest VoIP and cellular providers utilize this upstream carrier to provide connections for voice inbound and outbound.
Due to the way that telephone numbers work, we cannot set up a failover in the event that our main upstream carrier experiences an attack. We selected our upstream carrier based on multiple decades of great service and uptime, this is also why many of the other VoIP and cellular providers as well as largest organizations on the planet have chosen them.
Outbound calling can support failover and all of CallHarbor's outbound calling traffic has been migrated away from this upstream carrier who is experiencing an attack. As the attack is ongoing there may be periods of poor audio quality inbound, or inbound call failures.
If you are experiencing an issue inbound or outbound do not hesitate to reach out to CallHarbor we are here to help, we are still looking through all poor audio or call issues to determine cause and resolve where possible. In the event that the issue is caused by this upstream carrier attack we will inform you.
We are working with our other major carrier partnerships to build a plan in the event that this attack on this major carrier appears to extend in time. This would take some time to implement (due to porting restraints nationally) however we are prepared to protect you and your business.
CallHarbor is currently having no issues with its own network, or extension to extension calling; Furthermore some CallHarbor customers do not rely on this upstream carrier for service and will be unaffected by this attack.
If you are having trouble reaching CallHarbor support through our main line you may dial our alternative support line: 313-644-7500
We will continue to provide updates at https://status.callharbor.com
in order to be as transparent as possible regarding the current issue affecting VoIP providers nationally.
NOTICE: In the event of an emergency where 911 needs to be reached please utilize cellular networks where possible.
