No. We installed the system in late May and yes, we charged them for that. After the system crashed a few times, we convinced the customer to let us install the APC ups/surge protector.

Prior to that the customer was using a few generic 4-line phones for their admin people and had all of their telemarketers on single line phones. But they had never had a "phone system" before.

I'm anxious to see if the new dedicated circuit helps. Since May we've had two 1-week periods where the system did not crash at all, so we'll need at least a few weeks of stability to see if the problem is actually resolved.
