Voice-only with different codecs
Situation:
Voice-call between 201 (GSM-codec) and 301 (G711u codec)
- Traffic to and from Ext. 201 is Green
- Traffic to and from Ext. 301 is Red
- Traffic between Asterisk-boxes is Blue
Used filters in I/O-graph:
Filter-Black: proto=sip Filter-Red : ip.addr == 192.168.1.3 && ip.addr == 192.168.1.106 Filter-Green: ip.addr == 192.168.1.189 && ip.addr == 192.168.1.101 Filter-Blue : ip.addr == 192.168.1.106 && ip.addr == 192.168.1.101 Filter-Pink : ip.addr == 192.168.1.100 && ip.addr == 192.168.1.101
This doe not tell us which Asterisk box makes the conversion between the GSM codec and the G711u codec. Therefore we made another graph with the traffic meassured only in one direction.
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
