guys @ middle claim that the Asterisk is breaking the RFC and they are 
asking me to fix it on Asterisk as our company wants to use Asterisk. 
The "middle" does seems to work with many other SIP proxies.

I'm not developing it, but i'm working with a company thats trying to 
bring consumer VoIP by using Asteisk. I'm working on call processing 
system that uses astman. But i was pulled into this to get asterisk work 
with Middle. I dont have any other docs. i've asked for it. i'll post it 
  if i get one.

I've got logs from Middle, but i'm not sure how it may help. for the request

Asteisk is supposed to respond back to the IP on port 7062 (i was told. 
i'vnt read the RFC), but it send the request back on the port 7060, the 
originating port of the request.
