Tape 3A - a non POTS phone. Notice how much worse the audio quality is on calls made from this phone!
00:22 Dialing many things asks for a PIN (likely a voicemail system)

02:32 Let dial tone time out
03:22 Dial tone times out to reorder

Tape 3B / 3C - similar non POTS phones.

Tape 4A - 206-682
00:04 Direct dialing long-distance calls works!
00:15 Dialing 7 digits goes to intercept

Tape 4B - STTLWA06DS4 206-467 (phone class of service similar to phone in 4A)

00:00 - Dial 1-700-555-4141
00:10 - Get intercept from tandem, 077T.
00:35 - Dial a long-distance number directly, it works.
00:58 - Dial *66, get an intercept (feature not present on this line)
01:20 - Dial local call as 7 digits, get 10-digit intercept. Intercept is NOT Pat Fleet like on STTLWAELDS0!
02:05 - Dial 00 and get AT&T operator system, demonstrating this phone is PIC'd to AT&T.
03:15 - Dial 101-0288-1-700-555-4141 and get tandem intercept, 077T. Might explain why 1-700-555-4141 went here?
03:35 - Dial 101-0555-1-700-555-4141. This works. DNVR-SLTR.
04:04 - Dial AT&T operator (101-0288-0).

07:20 - Dial 555-1212 in non-CenturyLink area codes. (Presumably, they all get handled by AT&T?)

Tape 4C
00:00 - Dial 00
00:21 - Operator Lyla answers and confirms she's an AT&T operator.
00:30 - Dialing 101-0288-0 goes to the same system we just heard. It's a match!

Tape 5 - More VoIP shenanigans with the same phone as in tape 3A.
00:00 - You can dial * over and over again forever...
00:35 - When the switch hangs up, we get dropped to a busy tone locally by the ATA/ONT
01:21 - Even though *67 doesn't give recall dial tone, it's still processed by the switch.
        A call to a number that rejects anonymous calls drops to "busy" when dialed with *67.
01:49 - Redialing the same number without *67, the call connects normally, showing that *67 does do something.
02:23 - Dial a long-distance number
02:42 - When it answers, flash, and we get a never ending stutter dial tone. Brief flashes don't break.
02:56 - Finally, we hang up and pick back up, and seem to have lost our original call.
03:08 - Repeat to get the infinite stutter dial tone again. We can dial on it, but when we flash, it repeats, rather than conferencing.
03:32 - At this point, a flash drops us back to our original call.

Tape 6A - This phone is also on STTLWAELDS0, just like the phone in Tape 1.

03:50 - Dial 101-0288-0 again
04:06 - AT&T operator comes on the line
04:15 - Operator connects the call successfully
04:34 - Dial 101-0432-1-218-488-8463, call connects successfully
