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
