After about two weeks of seeing "unavailable" flash on the display unit every time a long-distance call came in, Crowley said she started to worry she had a problem and called the telephone company.
She said she went in circles for more than a month, talking to Bell Atlantic employees, long-distance companies and other local phone companies, who gave her conflicting answers.
Bell Atlantic admits Crowley's problem has a foundation in that Hagerstown-area customers are limited in the Caller ID information they can receive, said spokesman Paul Miller.
But the blame lies with AT&T - the dominant long-distance carrier in the area - which has "chosen not to interconnect" its information-relaying network with Bell Atlantic's local network, he said.
Miller said Bell Atlantic's hands are tied because it can't extend its network outside the regional calling area.
Calls in the Hagerstown regional calling area, including Washington, Frederick, Allegany and Garrett counties, are guaranteed to show up on the display unless the caller blocks the information.
And long-distance calls carried over MCI's and Sprint's networks should include Caller ID information, Miller said.
There are "anomalies" in the Hagerstown area because interconnectivity isn't flawless, said AT&T spokesman Dan Lawler.
However, it isn't because AT&T won't interconnect its caller identification-bearing network to Bell Atlantic's network, Lawler said.
It's not all Bell Atlantic's fault either, he said.
Miller said Crowley should have been told about her Caller ID's limitations when she ordered the service because it's company policy.
Advertisements for the service are generic, so they wouldn't mention the problem, "unique" to the Hagerstown area, Miller said.
Crowley has a few more days to decide whether or not she'll continue with the $7.50-per-month service, which she said seems to have improved a little in the past two weeks.
