Configure Voice-Port Signal Cama - Avaya 2330 Reference Manual

SIP Media Gateway commands

configure voice-port signal cama

Use this command to configure an FXO port for 911 calls.
By default, there is no CAMA configuration on any ports.
No two service areas in the existing North American telephony infrastructure supporting E911
calls have identical service implementations, and many of the factors that drive the design of
emergency call handling are matters of local policy and therefore outside the scope of this
document.
Local policy determines which Automatic Number Identification (ANI) format is appropriate for
the specified Physical Service Access Point (PSAP) location. The supported four types of ANI
transmittal schemes are based on the actual number of digits transmitted toward the E911
tandem. In each instance, the actual calling number is proceeded with a key pulse (KP)
followed by an information (I) field or a Numbering Plan Digit (NPD), which is then followed by
the ANI calling number, and finally by a start pulse (ST), STP, ST2P, or ST3P, depending on
the trunk group type in the PSTN and the traffic mix carried. The information field is one or two
digits, depending on how the circuit was ordered originally. For one-digit information fields, a
value of 0 indicates that the calling number is available. A value of 1 indicates that the calling
number is not available. A value of 2 indicates an ANI failure.
For a complete list of values for two-digit information fields, refer to SR-2275: Telcordia Notes
on the Networks at www.telcordia.com.

Value
Specifies 7-digit ANI transmission. The
calling phone number is transmitted, and the
Numbering Plan Area (NPA) is implied by the
trunk group and not transmitted.
Specifies kp–2–st transmission, which is
used if the PBX is unable to out-pulse the
ANI. If the ANI received by the AG2330 is not
as per configured values, kp–2–st is
transmitted. For example, if the voice port is
configured for out-pulsing a ten-digit ANI and
the 911 call it receives has a seven-digit
calling party number, the AG2330 transmits
kp–2–st.
Specifies 10-digit transmission. The E.164
number is fully transmitted.
