That's ok you don't need to change it at ipkall, you just need to make sure that the codecs you setup on the VoXaLot provider page are optimal.
Allow me to explain:
For example if ipkall supports ulaw, alaw and g729 and your phone only supported g729 and you were to put ulaw;alaw;g729 in the provider codec field, what you may find happen is:
ipkall <== ulaw ==> voxalot <== g729 ==> phone
This is the transcoding I speak of.
If however you changed your provider codec setting to just have g729, then one of these 2 pass-through scenarios are likely to happen:
ipkall <== g729 ==> voxalot <== g729 ==> phone
ipkall <== g729 ==> phone
i.e. no transcoding.
