POTS Protocol Whether the card is using MGCP or SIP protocol
Profile: Profile used that pre-populates many of the port attributes.
Description (Customer ID): Customer ID for the port. Refer to 7.2.7.
Prioritized Codecs Specifies the Codec capabilities advertised to the Call Agent:
- PCMU: G.711 mu law (specified in CCITT/ITU-T recommendation G.711)
- G726-32: CCITT/ITU-T recommendation G.726
- T38 - Use this mode to digitize the media for reliable transmission over IP networks
- All: all of the above
Note: Refer to the Release Notes for the iMAP product for details on T38
support.
Min. Packetization: The minimum number of milliseconds of voice data that can be encoded in a data
packet. This value is advertised to the Call Agent. The default is 20 msec.
Note: To support Call Waiting with Caller ID, this attribute should be set to 10
milliseconds.
Max. Packetization The maximum number of milliseconds of voice data that can be encoded in a data
packet. This value is advertised to the Call Agent. The default is 20 msec.
Note: To support Call Waiting with Caller ID, this attribute should be set to 10
milliseconds
Jitter Buffer Delay: Used with jitter buffering, this is the amount of time that the first packet is delayed.
This delay is then used to smooth out jitter on subsequent arrivals.
The default is 30 msec
Jitter Buffer Mode: The jitter buffer mode. A jitter buffer is used to compensate for the jitter in packet
arrival and out-of-order packets. A large jitter buffer causes increase in the delay and
decreases the packet loss. A small jitter buffer decreases the delay but increases the
packet loss.
DYNAMIC - This mode minimizes delays and is the default.
Voice Activity Detection: Specifies whether to advertise Voice Activity Detection (VAD) capability to the Call
Agent. VAD is used for silence suppression, and will reduce the transmission rate
during inactive speech periods while maintaining an acceptable level of output quality.
ON: VAD is supported. This is the default
Echo Cancellation: Echo Cancellation in ms for period capability is advertised to the Call Agent.
