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.

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
