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 windows of the remote (CID generating) VOIP unit. The CID
Name and Number appearing on the phone at the terminating FXS end
comes either from a central office switch (showing a PSTN phone number),
or the phonebook of the remote (CID sending) VOIP unit.
CID Manipulation
Enabled by default
with Caller ID
enable above
Disable
This is not implemented in the –SS series VOIPs.
Caller ID Manipulation is used whenever the user wants to manipulate the
Caller ID before sending it to the remote end. Caller ID Manipulation is
activated on the Interface Window. By enabling Caller ID option, you can set
manipulation to Transparent, User CID, Prefix, Suffix, or Prefix and Suffix.
Caller ID Manipulation is a feature, where the Caller ID detected from the
PSTN line can be changed and then sent to the remote side over IP.
CID Mode
Transparent,
User CID,
Prefix,
Suffix
The MultiVOIP is not allowed to modify the caller ID info and then send it
to the PSTN side. It only allows it to detect the caller ID from the PSTN line,
modify it and then send them via IP to the remote end point.
Transparent: the CID received from PSTN is sent out as such, without any
manipulation.
User CID: the CID received from PSTN is replaced by this User CID value.
Prefix: the CID received from PSTN is prefixed with this value.
Suffix: the CID received from PSTN is suffixed with this value.
