Resolved -
During the scheduled maintenance window, additional hardware and routes were installed as CallTower integrates additional data centers into its network. The integrated data centers and expanded network will provide customers with improved call paths and fewer hops to CallTower’s network. The change during the maintenance window modified routing with many of CallTower’s peering partners for internet traffic. Select peering partner’s routes experienced high latency on the new routing path. Engineers optimized those routes for the peering partners and CallTower has seen services normalize. Phones that were affected by this issue have now registered and full functionality has been restored.

Update -
CallTower engineers continue to work on identifying the root-cause in order to fully restore ASA connectivity. Although the majority of ASAs are functioning properly, a small subset of ASAs are unable to connect some or all phones at select customer locations. If a phone is unable to register, CallTower Support can assist by forwarding the phone number to a registered phone or off-network number; additionally, Cisco 88XX model phones can be rebuilt as Edge phone and connect through the internet. Please send any request for forwarding or rebuilding phones to support@calltower.com.
