Summary:                    chan_sip will not retransmit an ACK
Description: 
In commit 204243 it was added a check on whether to retransmit an ACK or
not. In my case this breaks retransmission in the following scenario:
-> INVITE
<- 100 Trying
<- 180 Ringing
<- 200 OK SDP
[ACK is lost]
<- 200 OK SDP
<- 200 OK SDP

This scenario was between two asterisk acting as SIP clients and ser acting
as server.
