Incoming trunk calls will ring all unblocked telephones that have an unused
line (primary or secondary). The unused line's lamp will flash. If both lines
are unused, the primary line will flash. If the telephone is on-hook, it will
ring; if the telephone is off-hook, there will be a single buzz.
When a user goes off-hook in ESAM mode, the telephone will get dial tone
from the card. If the user dials the trunk access digit configured for outside
lines (the default digit is 9), the dial tone will not break until the next digit
is dialed. Digits dialed after the trunk is accessed will cause the card to
switch DTMF for the appropriate digits into the voice path toward the CO
for 50 milliseconds (ms) ON and 50 ms OFF.
If the user dials a valid extension that has an unused line, the telephone
will ring and the unused line's lamp will flash (if both lines are unused, the
primary line will flash). If the user dials an invalid extension, the user's
telephone will get a re-order (pulsed) dial tone. If the dialed telephone has
both lines in use, the calling telephone will get a busy signal.
When a call comes into a trunk, all telephones that are on-hook with an
unused line will ring and the lamp associated with the unused line will flash
(if both lines are unused, the primary line's lamp will flash). Telephones
that are off-hook with an unused line will get a flashing lamp associated
with the unused line and a warning tone. The first user to answer the call
will be connected to the ringing trunk. The user can put a call on hold or
transfer the call in the same manner as is used by the local system; both
blind and announced transfers are supported.
