I do not know if it is fixed in Asterisk 1.6, but the bug is still in

Asterisk             SIP proxy          phone1      phone2


The 200 will be ignored by Asterisk.

In pedantic mode Asterisk learns the totag in the first response and 
ignore all other responses with different totag. Thus, Asterisk can not 
handle multiple early dialogs. The bugfix (without making Asterisk real 
multi-early-dialog-aware) would be to learn the totag only in the final 
response, not in the provisional response.
