Hi,
I am new to the SIP NAT issue so it may be a dam question.
I draft-ietf-sipping-nat-scenarios-00.txt section 4.3 the use of B2B allows
two SIP-UA behind different NATs to talk SIP. what if both UA are behind the
same NAT (B2B). Does B2 suppose to detect it and not to change the SDP
message? What if there are few B2B behind the same NAT (suppose that one B2
can't handle all the traffic)?
Something like:
-------------------------
| |
| NAT |
| |
| |
------------------------
| |
| |
------- -------
|B2B | | B2B |
| | | |
------- -------
/ \ / \
/ \ / \
UA UA UA UA
10.1.1.2 10.1.13 10.1.2.1 10.1.2.2
and 10.1.1.2 wants to talk to 10.1.2.2 how the RTP will go ?
Thanks.
