This language developed in time, at the beginning just few statements 
and methods were available, and they seemed to be enough for a SIP 
router. This language and its interpreter allow a lot of operations that 
help to speed up the processing and control what can be done in the 
configuration file -- ser was designed to be very fast, and a customized 
language was the most suitable.

Could be an alternative to embed some language in the configuration, but 
will require a lot of development and maybe internal structure changes. 
Also, the config will be a wild garden, maybe more flexible, but more 
exposed to troubles.
