between the first and second rings of the call.
Caller ID
enable
Y/N
Caller ID information is a description of the remote calling party
received by the called party. The description has three parts: name
of caller, phone number of caller, and time of call. The ‘time-of-call’
portion is always generated by the receiving MultiVOIP unit (on FXS
channel) based on its date and time setup. The forms of the ‘Caller
Name’ and ‘Caller Phone Number’ differ depending on the IP
transmission protocol used (H.323, SIP, or SPP) and upon entries in
the phonebook screens of the remote (CID generating) voip unit. The
CID Name and Number appearing on the phone at the terminating
FXS end will come either from a central office switch (showing a
PSTN phone number), or the phonebook of the remote (CID sending)
voip unit.
The Caller ID feature has dependencies on both the telco central office and the MultiVOIP phone book. See
discussion below.
