HI
 
I have asterisk 1.6.13 running. My ATA are connected via vpn (openvpn)
 
Out going calls from asterisk to the ata works fine
Incoming calls from the ata to asterisk cuts off with the error msg
 
Maximum retries exceeded on transmission 70854efe-4157e3a8 at 10.168.7.103 for 
seqno 102 (Critical Response) -- See doc/sip-retransmit.txt.
[Dec  6 13:52:43] WARNING[3921]: chan_sip.c:3858 retrans_pkt:
 Hanging up call 70854efe-4157e3a8 at 10.168.7.103 - no reply to our critical 
packet (see doc/sip-retransmit.txt).

I been googling this error and it was mentioned to use
t1min= 500 however its only delaying the problem.
 
any ideas on what is the cause of this problem.
Only 2-3 atas are having this problem the rest are fine.
 
Here is the sip debug
the sip invites are not being received
and in one of the message a busy response was sent back.
