Calls to and from IP devices can require conversion to the audio codec format being used by the IP device. In the IP Office this conversion is done by voice compression channels. These support the common IP audio codecs G711, G723 and G729a. For the IP Office 400 control units, channels can be added by fitting Avaya IP Office 400 VCM Cards.
