[SR-Users] Diversion header authentication

Thank you Daniel and Morten for your assistance and prompt reply. To use the tobody transformation, i see that i would need to upgrade to 4.1 right? Im currently on 3.3. I tried the below code: $var(i)=0; while($(hdr(Diversion)[$var(i)]) != $null ) { $avp(s:divhdr) = $(hdr(Diversion)[$var(i)]); avp_subst("$avp(s:divhdr)", "/.*sip:(.*)(@.*)/\1/"); xlog("L_WARN", "$avp(s:divhdr)"); if (!is_user_in("$avp(s:divhdr)", "7")) { sl_send_reply("403", "NOT ALLOWED"); exit; }; $var(i) = $var(i) +1; } However, it seems like group module cant parse the output 313 as seen below: Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: WARNING: <script>: 313 Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: ERROR: group [group.c:114]: failed to parse URI <313> Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: ERROR: group [group.c:158]: failed to get username@domain A bigger issue is that a certain client is sending more than one diversion header with different format as seen below: Diversion: <tel:22030009>;reason=no-answer;screen=no;privacy=off Diversion: "Solonas A" <sip:16@10.10.10.22>;reason=unconditional So in this case i cant really know how to extract the diversion number using a static substitution. Is there a way to adapt to different formats to extract the diversion number?
