second rings of the call.

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.
CID Manipulation

Disable
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 Screen. 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 will be sent out as such, without any
manipulation.
User CID: the CID received from PSTN will be replaced by this User CID value.
Prefix: the CID received from PSTN will be prefixed with this value.
Suffix: the CID received from PSTN will be suffixed with this value.
FXO Supervision
When the selected Interface type is FXO, the Supervision button is active. Click on this button to access call
answering supervision parameters and call disconnection parameters that relate to the FXO interface type.
