Re: [Sip] Requirements on Reason information. New I-D

I understand the problem you want to solve. I have
no issue with interworking with other networks. 
My main issue is attempting to *identify* the network
you are interworking with via the Reason: header.
This is the slippery slope I want to avoid. It 
quickly becomes very nasty in more complex topologies
where you may dip into the PSTN-space more than once.
