RTP Packet Size - (Real-time Transport Protocol) defines a standardized packet format for delivering
•
audio and video over IP networks. The default is set to 20, and is adjustable from 10 to 60
milliseconds.
Codec settings - Set the order that each Codec will be used. When the system gets busier, it will
•
automatically increase the compression, to decrease the traffic (voice over IP packets), to ensure that
all of the calls can be completed with the best possible voice quality.
DTMF Type - Select between transmitting DTMF tone or SIP-INFO method. Generally, this will be set to
•
DTMF Type.
Hold Recall Time - The recall feature pertains to calls that are parked, on hold, or calls that have been
•
transferred to another extension. Calls which go unanswered after the preprogrammed time are
"Recalled" to the extension which initiated the park, hold or transfer. This timer is used to ensure that
calls do not go unattended. At default, the timer is set to 60 seconds, and can be adjusted to 30, 60,
90, 120, 150, 180, 210, 240, 270, 300.
FXS (Single Line Telephone)
FAX Support - (also known as Fax Detection) can be set to either G711_Pass (passes the signal directly
•
through the system) or T38 allows fax transmission, in real time, over an IP Network.
Caller ID Method - Caller ID, in the US, is a FSK signal that is passed between the first and second ring.
•
However, the X-50 has the ability to compensate for other types of Caller ID Protocol - FSK before
ring, FSK after ring, DTMF before ring, DTMF after ring.
Interdigit Timeout - At default the X-50 is set to 5 seconds, and adjustable from 2 to 9 seconds.
