Hawaiian Telcom has said it will try to fix intermittent phone service for at least 100 business customers across the islands  between 11 p.m. Tuesday and 2 a.m. Wednesday.

Customers may see more intermittent service during those times, but company officials hope to have the problem resolved by 2 a.m.

Since late morning, the company has received about 100 confirmed reports from Business All-In-One customers, including the Honolulu Star-Advertiser, experiencing disrupted phone service, according to Ann Nishida Fry, Hawaiian Telcom spokeswoman.

The company started receiving reports at about 11 a.m.

Nishida Fry said the source of the trouble stemmed from a call processing problem with a server that provides a “virtual switchboard.” She did not have an estimate of when service would be fully restored.

Calls should go to voicemail when the phone service is down and customers should be able to access their voicemails from a non-BAIO line, Nishida Fry said.
