The question about extension of an H.248 package.

Hello Sasha,

There is no hard rule of what to propose. It really depends on the type of

information you want added.

I think the only time the package extension should be used is if the added

properties/signals/events provide a set of functions of their own right.
e.g. 
would it makes sense that these properties could be a package by
themselves but 
need another package to operate. For example: The tone gen package. The
DTMF was 
added as a extension package as DTMF generation is its own subset
functionality 
but is related to the generation of tones.

Regards, Christian
