testing IAX2 trunking

Situation:

Schematic overview of all PC's running which software.

Conference-Voice-call between 201, 202 (G711u-codec) and 301 (G711u codec) X-lite on ext. 301 was combining the conference.

  • Traffic to and from Ext. 201 is Green
  • Traffic to and from Ext. 202 is Pink
  • Traffic to and from Ext. 301 is Red
  • Traffic between Asterisk-boxes is Blue in one direction and black in the other

Used filters in I/O-graph:

Filter-Black: ip.src == 192.168.1.101 && ip.dst == 192.168.1.106
Filter-Red  : ip.src == 192.168.1.3   && ip.dst == 192.168.1.106
Filter-Green: ip.src == 192.168.1.189 && ip.dst == 192.168.1.101
Filter-Blue : ip.src == 192.168.1.106 && ip.dst == 192.168.1.101
Filter-Pink : ip.src == 192.168.1.100 && ip.dst == 192.168.1.101

Number of packets. Red was the SIP-phone combining the conference (Auto-Conference). All using G711u codec.
