Understanding MGCP
The list contains the following:
• Events that were accumulated (but not notified)
• Events that were treated according to the digit map (but not matched yet)
• The final event that triggered the detection or provided a final match in the digit map
Events that have been accumulated according to the digit map are grouped in a single string. Examples
of observed actions are:
• hu
• 8295555T
• hf, hf, hu
Connection Parameters (P)
When the call agent terminates a connection, it collects statistics (connection parameters) on the
execution of the connection. In the general case where a connection has two ends, the delete connection
command is sent to both gateways involved in the connection, and therefore the statistics are collected
from both.
Connection parameters are encoded as a string of type and value pairs, where the type is a two-letter
identifier and the value is a decimal integer. Types are separated from values by an equals sign.
Parameters are separated from each other by a comma.
Table 4-6 lists Connection Parameter types.
Table 4-6 Types of Connection Parameters
Connection Parameter Name Code Value
Packets Sent PS Total number of RTP data packets transmitted by the sender
since starting transmission on this connection.
1
Octets Sent OS Total number of payload octets (not including header or
padding) transmitted in RTP data packets by the sender since
starting transmission on the connection.
1
Packets Received PR Total number of packets received by the sender since starting
reception on the connection.
2
Octets Received RO Total number of payload octets (not including header or
padding) received in RTP data packets by the sender since
starting transmission on the connection.
2
Packets Lost PL Total number of packets that were not received on the
connection, as derived from gaps in the sequence number.
The value is zero if the connection was set in “send only”
mode.
