There is no need for special modules for this. Just accept these SIP
requests.

The problem might be how you known you should accept these messages.
This can be done with following (but not limited to): 
- a simple if($si=="1.2.3.4")
- using is_in_subnet from ipops
- ds_is_from_list if you have these endpoints in a dispatcher
- the permission module
- maybe even a challenge/response with a authenticate function
