cvVoIPCallHistoryMaxPtime

Module: CISCO-VOICE-DIAL-CONTROL-MIB

OID (symbolic): CISCO-VOICE-DIAL-CONTROL-MIB::cvVoIPCallHistoryMaxPtime

OID (numeric): 1.3.6.1.4.1.9.9.63.1.4.2.1.38

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The object indicates the maximum amount of media that can be encapsulated in a payload. Supported value is 20 msec. This object is not instantiated when the object cvVoIPCallHistoryCoderTypeRate is not equal to gsmAmrNb enum.

What is cvVoIPCallHistoryMaxPtime?

This Integer32 (20-100 ms) indicates the maximum amount of media that can be encapsulated in a single RTP payload for the call, with 20 msec being the only supported value, and it is only instantiated for the gsmAmrNb coder. Administrators use it to confirm the packetization interval negotiated for AMR-NB calls, which affects both bandwidth overhead and playout latency. For example, verifying this object reads 20ms confirms the gateway is using the only currently supported maximum payload interval for that AMR-NB call.

Examples
