Hello,

do not write private emails from mailing list discussions, if not sensitive data was asked explicitly.

If there is no rule to breaking the loop, after some time the message gets very big.

Cheers,
Daniel

Thanks for respond. I just have used forward() based on RURI.

got

0(2558) ERROR: <core> [msg_translator.c:1835]: ERROR: build_req_buf_from_sip_req: out of memory

With maxfwd it works like a charm. http://paste.ubuntu.com/1204093/

Hi, List.

I'm using sipsak to fire some predefined sip message with Max-Forwards: header equal 0 to test mf_process_maxfwd_header function. I'm doing this exclusively for learning purpose. As far as we know, this exported function from maxfwd module services only for adding Max-Forwards header, decrement or detect Max-Forwards: 0 header to prevent loops. So, my question guys, how can I create this loop in my lab, with two proxies for example? What message should I craft?

what kind of message are you looking to craft?

Looping from one proxy to another can be achieved with t_relay("_the other proxy address_") function from tm module.

Cheers,
Daniel
