[Serusers] Logging problem

I have a sip server running purely as a proxy, all it does is forward requests onto a remote sip box. I want to log all the requests that go through it, and use this to create billing records, but I can't get anything out of the server. I have setup the logging level to 8, but only get a few messages at startup. I enabled the acc.so module, in hope of creating accounting information that way, and also nothing. I know this must be because all my requests are forwarded, but I should get something surely... Any ideas what I'm doing wrong? debug=8 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) fifo="/tmp/ser_fifo" ... loadmodule "/usr/local/lib/ser/modules/acc.so" ... # -- acc params -- modparam("acc", "log_level", 8) modparam("acc", "log_flag", 1) modparam("acc", "log_fmt", "mfctios") alias="acme.co.uk" route[0]{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; # record transaction using accounting module setflag(1); # Record route all messages to make sure that subsequent messages # go through sip proxy server. record_route(); # forward all requsts to --- forward (192.168.1.2, 5060 ); }
