Summary:                    Wrong handling of INVITE with Diversion tag when
Asterisk has seen the callid before
Description: 
Same scenario as 15095, but on 1.6 this time with very different (worse)
behaviour. Same hardware and operating system as that report.

When asterisk receives a call (via PSTN in this case), sends an INVITE to
a SIP proxy, that SIP proxy adds a Diversion tag and sends it back to
asterisk to get back to the PSTN, the call doesn't complete an asterisk
complains with a peculiar error:
[Sep 28 15:41:24] WARNING[32316]: chan_sip.c:4224 create_addr: No such
host: 5555555

5555555 is the number being forwarded to, and is nowhere specified as a
destination host.

sorry but it looks like your proxy doesnt do it right. 
pending on rfc 5806 a sip proxy should send a 30x message back with the
diversion header or create a new request (invite) with the diversion
header, but your proxy does not change the caller-id,branch and from tag so
asterisk thinks its a response not a request and the diversion header
finally brakes this dialog.
