The suspect message is generated by openser internally (8). Thus the max-fwd module wont help - I guess.

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..

Hi Nick,

I made a fix on SVN trunk - TM will include a Max-Forwards header in the local generated ACK and CANCEL. Let me know if works ok for you.

Thanks, but it wasn't my problem but that of Fangyu Ling.

I'm sure he'll be happy though!!
