[SR-Users] is $td.did avp a normal avp?

domain module sets $td.did at lookup_domain call. $td.did seems to be a normal avp, because i can print its value with xlog by referring to it as $avp(td.did). however, its value is gone at failure route, which makes me suspect that $td.did is not really a normal avp. in route block i have $avp(did) = $td.did; xlog("L_INFO", "at t_relay: <td/td.did> = <$avp(did)/$avp(td.did)>\n"); if (t_relay()) exit; branch route, onreply route, and failure route are set when the above t_relay() takes place. at the end of branch route block, i have xlog("L_INFO", "at end of contact branches: <did/td.did> = <$avp(did)/$avp(td.did)>\n"); and at the beginning of onreply route block: xlog("L_INFO", "at beginning of onreply: <did/td.did> = <$avp(did)/$avp(td.did)>\n"); and at the beginning of failure route block: xlog("L_INFO", "at beginning of contact failure: <did/td.did = <$avp(did)/$avp(td.did)>\n"); when i make a call, i get to syslog: Apr 22 15:53:27 sip /usr/sbin/sip-proxy[13706]: INFO: at t_relay: <td/td.did> = <test.fi/test.fi> Apr 22 15:53:27 sip /usr/sbin/sip-proxy[13706]: INFO: at end of contact branches: <did/td.did> = <test.fi/test.fi> Apr 22 15:53:27 sip /usr/sbin/sip-proxy[13708]: INFO: at beginning of onreply: <did/td.did> = <test.fi/<null>> Apr 22 15:53:27 sip /usr/sbin/sip-proxy[13705]: INFO: at beginning of contact failure: <did/td.did = <test.fi/<null>> why is it that $avp(did) value has been preserved from route/branch route block to onreply/failure blocks, but value of $avp(td.did) is not? i'll cc to jan in case he is not on this list. -- juha
