Controlling IAX bandwidth

In the iax.conf config file the following parameters can be used to adjust the used bandwidth.

bandwidth=low
disallow=all
allow=gsm

When the bandwidth is set to low, Asterisk will use the codec with the lowest bandwidth available. For more info on codecs and their bandwidth usage, see Audio_Codecs

Controlling SIP bandwidth

In the sip.conf:

maxcallbitrate=384

This will tell the sip-device what bandwidth is available (in kbps). This value defaults to 256 kbit/s.

Possibilities of X-lite

  • "Zero Touch bandwidth detection"
  • QoS maybe not implemented in the free version (is an advertised feature for the non-free version)
  • Both X-lite and Eyebeam support Auto Bandwidth - Automatically measures available bandwidth and adjusts codec selection accordingly. Perhaps is Asterisk or IAX reporting the available bandwidth.
