I spent a little time tracing through the code and couldn't figure out
what's going on.
Just a note for the future that it'd be worth figuring out why the
client is repeating SETCLIENTID+SETCLIENTID_CONFIRM or
EXCHANGE_ID+CREATE_SESSION. I understand why it might be needed for
trunking detection when there are multiple addresses involved, but
otherwise it seems unnecessary.
