[VoIP] Ernest Telecomm 7D-3 Payphone

[Jayson Smith]

Hi,
On the 5ESS I was served out of before switching to cable, if you do a sort
of long flash at a dialtone, such that you get a new dialtone, fifteen
times, it cuts the line off, no talk battery, for a few minutes. When the
line comes back, there are a few weird clicks. I don't know what purpose
this serves. While out of service, the line acts like it's busy when it gets
incoming calls.
