system is free, speech channel will be connected by relay, while a preliminary
tone(electronic chime bell) is supplied to the telephone and speaker(s) for 2 seconds.
In case that paging system is busy, a busy tone is heard from telephone handset.
3.3 Shore Tel. external call
The user of extension given with this feature priority can make an outgoing call
through trunk by dialing this feature digit "9" and wanted number. After dialing digit
"9", make sure of a dial tone from trunk. And then dial the wanted number. If all
trunks are busy, a busy tone will be heard. In this case, wait for some time after
hook-on and retry later, or make an external call-back.
TRUNK OIAL "9" ANO WANTEO NUMBER
If an incoming call is present on a trunk, pre-assigned extension(one, two or three
extension) receives an external ring. The user of pre-assigned extension can make a
response to the incoming call by hooking off the telephone handset during external
ringing.When an user dials digit "9" to make an external call, if there is a incoming call
on a trunk, incoming call is connected firstly.
3.4 Internal Call-Back

party will hear a ring-back tone from the handset for 1 seconds, indicating internal
call-back activated to the called party, then hear a busy tone and speech channel for
calling party will be reset.
HOOK_FLASH ANO OIAL "Reserve Oial NO"
If both parties, call-back calling and call-back called, become free, internal call-back
calling party receives an internal ring for 30 seconds and will be excluded from
internal call-back service if call-back calling party doesn't make a response within that
time by hooking off the telephone handset. If internal call-back calling party makes a
response within 30 seconds, he hears a ring-back tone and call-back called party
receives an internal ring. Following procedure is the same as that of inter-party call.
In case that internal call-back called party is engaged in another call procedure
before call-back calling party makes a response, then the calling party hears a busy
tone from the telephone handset when he hooks off in response to internal Call-back
ringing. But the internal call-back remains effective.
3.5 Shore Te!. external Call-Back
When making an outgoing call, if all trunks are busy and external calling party wants
to make an external call-back, then confirming a dial tone from telephone handset
and dials a external call-back digit "Reserve 9". Calling party will hear a ring-back
tone from the handset for 1 seconds, indicating external call-back activated. But,
when the external call-back queue is full, the party hears a busy tone and is
released from speech channel. If any trunk becomes idle, external call-back activated
party receives an external ring. By hooking off the handset, external call-back activated
party seizures a trunk automatically, and hears a dial tone from trunk. In this case,
dialing telephone number only without an external call digit "9" makes an external call.
When there are several external call-backs in the queue, priorities will be honored first
and then time sequence.
