[SR-Users] Problems with pseudo-variables

Hello, I am using kamailio ims extensions and I am observing some problems with pseudo-variable handling. On the s-cscf the pseudo-variables are not 'translated' into the real values. When using xlog like this: xlog("L_ERR", " found pai: $ai time [$Tf] \n"); I am finding : tail -f /var/log/syslog | grep found invlcscs /usr/sbin/kamailio[21689]: ERROR: <script>: found pai: $ai time [$Tf] However on the p-cscf the same case is correctly treated: xlog("L_ERR", " found pai: $ai time [$Tf] \n"); invlcpcs /usr/sbin/kamailio[20540]: ERROR: <script>: found pai: sip:0188888881@open-ims.test;transport=UDP time [Fri Aug 19 14:05:44 2011] I am using 3.1 kamalio version and I have added pv and xlog modules on the s-cscf. Why is the S-CSCF unable to read pseudo-variables?Could anybody please help me? Thank you. RR.
