#define BUFF_BW   300

Number of bandwidth history entries retained in the rolling history buffer.

Function Documentation

iax2_packet_analyse()

void iax2_packet_analyse ( tap_iax2_stat_t * statinfo, packet_info * pinfo, const struct _iax2_info_t * iax2info )

extern

Analyzes an IAX2 packet and updates statistics.

This function analyzes an incoming IAX2 packet, updating various statistics such as payload type changes, time differences, jitter, and delta times.

Parameters

statinfo	Pointer to the statistics structure to be updated.
pinfo	Pointer to the packet information structure.
iax2info	Pointer to the IAX2-specific information structure.

< Number of bandwidth history entries retained in the rolling history buffer.

< Number of bandwidth history entries retained in the rolling history buffer.
