Hi,
maybe the simplest way will be to use the maxfwd module. See:
http://www.openser.org/docs/modules/1.2.x/maxfwd.html#AEN70

Dear All:
I've tried many methods to add Max-Forwarsd header into ACK message
(message 8), all methods I tried were fail.
According to RFC 3261 8.1.1.6, Max-Forwards must exist in this ACK
message. Can anyone tell me how to add a header into ACK message? Thank
you very much.

if(is_method "ACK") && !search(Max-Forwards:)){
insert_hf("Max-Forwards: X ", "" )
};
Something like this (I guess you'll need a number in the max forwards
header, etc)in the correct place (look at the documentation for
insert_hf()) should do the job..
