Summary:                    200 OK is not accepted when SIP INFO in early dialog
Description: 
Scenario :
Extension 6789 calls 1234 
1234 points to aa_3 (IVR) in the context
When aa_3 is playing, 6789 press 1234 (Extension)
* then sends an INVITE to a PSTN Gateway (Mediatrix 3532)
Because of PSTN, the Mediatrix 3532 sends a 183 with SDP to *
6789 now hears an IVR on the PSTN and press 1 and 2 (choices in PSTN IVR)
The two SIP INFO messages are sent to *
The PSTN finally connect and the Mediatrix 3532 sends the 200 OK to the *

Asterisk never answers this 200 OK and the call gets drop.

Attached is the SIP debug + core and verbose 5 (asterisk -Tvvvvvdddddngc |
tee /tmp/verbosedebug.txt) and an ethereal capture (Call ID between
Asterisk and Mediatrix 3532) for easy reading.
