[ATLSIP] remove unwanted codec option

[OSS F. A. <ope...@op...>]

is it possible by any chance to remove some source file so as to be able to compile dialer with only some of the codecs as most of them my softswitch doesnt support and i dont need them also but cant figure out a way to avoid them from being compiled as well. im looking for only G729 and mayb GSM, G723, G711u, thats it
