Experimental Setup
In order to gain inside in the bandwitdh usage when SIP-phones use different codecs, the following experimental setup is used. A voice-call has been established between SIP-phone 201, which uses the GSM-codec and SIP-phone 301, which uses the G711u-codec.
Results
With WireShark data has been collected and the following filters are used in the 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
Legenda:
- Blue: Traffic between the Asterisk-boxes.
- Red: Traffic to and from SIP phone 301.
- Pink: Traffic to and from SIP phone 202.
- Green: Traffic to and from SIP phone 201.
Conclusions
- Tsah
