Poor audio or music on hold with Trixbox

If you are using Trixbox (or probably any Asterisk distribution) with SIP trunks and the Dahdi dummy driver and experiencing poor audio or music on hold then it may be worth changing the ‘internal_timing’ setting.

This can be set be editing the file – /etc/asterisk/asterisk.conf file and making sure that the following 2 lines are not commented out (they should not have a ; in front of them) –

internal_timing = yes

In some cases this can improve the audio quality dramatically.
