[SR-Users] UAC, parsing auth header failed

Hello, our voip provider requires autentication to voip services. Trying to use UAC module, I get "401 Unauthorized" packet, but looks like all ser based programs have problems to parse this packet. Can somebody make a patch to fix this? Here is message from logs: Jun 17 15:01:42 kamailio /usr/sbin/kamailio[1291]: ERROR: uac [auth_hdr.c:267]: parse error in <DIGEST realm="BroadWorks",qop="auth",algorithm=MD5,nonce="BroadWorksXgajlo4shTqsrkgdBW"> around 0 And ngrep sniffed packet: SIP/2.0 401 Unauthorized.

I tryed to look at sources, but this "C" code is too complicated for me. :-( SAL
