[Serusers] Multiple Registrations

Hi, When we have a situation in which a PC changes IP addresses (like on dialup), we end up with multiple registrations (see below). Is it possible to configure SER so that it only has the latest registration? [root@maui ser]# serctl ul show rvilla <sip:rvilla@200.58.193.72:5060;transport=udp>;q=0.00;expires=2773 <sip:rvilla@200.58.203.236:5060;transport=udp>;q=0.00;expires=3194 <sip:rvilla@200.58.203.61:5060;transport=udp>;q=0.00;expires=3544 On a related note, the registrar README says: "Name: lookup Params: table - Name of table that should be used for the lookup Desc: The functions extracts username from Request-URI and tries to find all contacts for the username in usrloc. If there are no such contacts, -1 will be returned. If there are such contacts, Request-URI will be overwritten with the contact that has the highest q value and optionally the rest will be appended to the message (depending on append_branches parameter value)." ....but as you can see all 3 contacts have the same "q value" (whatever that stands for). How does one resolve such an issue? Thanks, Ricardo
