The FXS voice subscriber line sends the calling identity information to the called telephone. The calling
identity information is sent to the called telephone through FSK) modulation between first and second
rings. Therefore, the called user must pick up the telephone after the second ring to be sure that the
calling identity information is sent and received correctly. Otherwise, the calling identity information
might fail to be displayed.
CID on the FXO voice subscriber line
The FXO voice subscriber line receives the calling identity information from the PBX. The FXO interface
receives the modulation information of the calling identity information from the PBX between the first and
second rings. This is the default situation. You can configure the Time for CID Check on the FXO line
configuration page to configure the time for CID check.
The calling identity information then undergoes FSK demodulation and parity check. The function of
sending calling identity information is checked after the parity check succeeds. If the function is enabled,
the calling identity information (indicating that the calling identity information is received) is sent.
Otherwise, the character P or O is sent.
Support for SIP voice service of the VCX
