Hi,

It doesn't work, with the 'c' flag all the c= tags remain unchanged.

Check the new 'c' flag in 1.1 release:

 Hello,

 I use OpenSer with Cisco AS5300/5350/5400 with IOS 12.3.
 When Cisco sends an OK 200 SIP message to OpenSer, there are two "c=IN
IPV4"
...
  tags in sdp body with the same IP address.
 The nathelper module only replaces the last occurence of c= tag so 
 some SIP clients works wrong because those  get the first IP from the first 
"c="
...
  tag...

 How can i replace the all occurences of "c=" tag in sdp body with the 
 help of nathelper?

 Thx,

 Antal
