Hi,
I'm working on a mini version of zap project, and I was wondering how to
remove the "optional"
modules without affecting the essential sip/sdp/rtp/codecs parts.
my version will remove : contacts,
missed/received...calls,logs,configuration,media offer
also it will use only one identity,one codec (no choices)
UI will finally contain only a uri field with a "call" button.

So how to remove easily these modules,and keep only the unconfigurable basic
service

Thanks
