According to Zaptel Sample configuration, you should be able to set PCM encoding by using the following command
alaw=1-4
# Overiding PCM encoding # ~~~~~~~~~~~~~~~~~~~~~~ # Usually the channel driver sets the encoding of the PCM for the # channel (mulaw / alaw. That is: g711u or g711a). However there are # some cases where you would like to override that. 'mulaw' and 'alaw' # set different such encoding. Use them for channels you have already # defined with e.g. 'bchan' or 'fxoks'. #mulaw=1-4 #alaw=1-4
For more information about how to configure Zaptel please read:
Additionally, I would like to mention that Zaptel has been discontinued and has been replaced by DAHDI (the Digium Asterisk Hardware Device Interface). See the following announcements:
