[SR-Users] weird dp_translate result

i have this piece of config code: modparam("dialplan", "attrs_pvar", "$var(plan)") ... xlog("L_INFO", "Translating <$var(calling_number)> based on dpid 4\n"); if (dp_translate("4", "$var(calling_number)")) { xlog("L_INFO", "Found attrs <$var(plan)>\n"); ... dpid 4 has three entries: 109 4 10 1 ^\+1 0 na 107 4 10 1 ^\+358 0 fi 108 4 10 1 ^\+46 0 se thus in each entry attrs field has some two letter value. when the above piece of code is executed, i get to syslog Aug 31 19:06:51 wheezy2 /usr/sbin/sip-proxy[7162]: INFO: Translating <+35892345670> based on dpid 4 Aug 31 19:06:51 wheezy2 /usr/sbin/sip-proxy[7162]: INFO: Found attrs <0> if i restart the proxy, attrs value may change to some other bogus value. any ideas? -- juha
