<div dir="ltr"><div>I have a Kamailio server that has:<br><br>modparam("registrar", "max_contacts", 2)<br><br></div>But
 recently I noticed some users have more than two records in the 
location table. For example one of the users has three different records
 with nearly the same information. The records are as follows. Is this 
behavior normal? (I am using Kamailio 4XX).<br><br>*************************** 1. row ***************************<br>           id: 171296745<br>         ruid: uloc-2c69-59db6c73-7ca-132d92<br>     username: 999999999999<br>       domain: NULL<br>      contact: <a href="http://sip:999999999999@5.106.35.18:10362" target="_blank">sip:999999999999@5.106.35.18:<wbr>10362</a><br>     received: sip:<a href="http://5.106.35.18:10361" target="_blank">5.106.35.18:10361</a><br>         path: NULL<br>      expires: 2017-11-14 08:45:50<br>            q: -1.00<br>       callid: XpCnmaAhRF<br>         cseq: 43<br>last_modified: 2017-11-14 08:44:50<br>        flags: 0<br>       cflags: 64<br>   user_agent: android_1.1.0_samsung_SM-<wbr>E500H_<wbr>7b271714c08b942aa821fc756cdd2e<wbr>890a37069e/1.1.0 (belle-sip/1.4.2)<br>       socket: udp:<a href="http://192.168.103.21:5060" target="_blank">192.168.103.21:5060</a><br>      methods: NULL<br>     instance: <urn:uuid:8369ef6e-202b-4844-<wbr>8928-492a7678c269><br>       reg_id: 0<br>    server_id: 11369<br>connection_id: -1<br>    keepalive: 1<br>    partition: 14<br>*************************** 2. row ***************************<br>           id: 171296746<br>         ruid: uloc-2c69-59db6c73-7f2-eb5d92<br>     username: 999999999999<br>       domain: NULL<br>      contact: <a href="http://sip:999999999999@5.106.35.18:10362" target="_blank">sip:999999999999@5.106.35.18:<wbr>10362</a><br>     received: sip:<a href="http://5.106.35.18:10361" target="_blank">5.106.35.18:10361</a><br>         path: NULL<br>      expires: 2017-11-14 08:45:50<br>            q: -1.00<br>       callid: BzMKuyJN8C<br>         cseq: 50<br>last_modified: 2017-11-14 08:44:50<br>        flags: 0<br>       cflags: 64<br>   user_agent: android_1.1.0_samsung_SM-<wbr>E500H_<wbr>7b271714c08b942aa821fc756cdd2e<wbr>890a37069e/1.1.0 (belle-sip/1.4.2)<br>       socket: udp:<a href="http://192.168.103.21:5060" target="_blank">192.168.103.21:5060</a><br>      methods: NULL<br>     instance: <urn:uuid:8369ef6e-202b-4844-<wbr>8928-492a7678c269><br>       reg_id: 0<br>    server_id: 11369<br>connection_id: -1<br>    keepalive: 1<br>    partition: 23<br>*************************** 3. row ***************************<br>           id: 171296747<br>         ruid: uloc-2c69-59db6c73-80f-541d92<br>     username: 999999999999<br>       domain: NULL<br>      contact: <a href="http://sip:999999999999@5.106.35.18:10362" target="_blank">sip:999999999999@5.106.35.18:<wbr>10362</a><br>     received: sip:<a href="http://5.106.35.18:10361" target="_blank">5.106.35.18:10361</a><br>         path: NULL<br>      expires: 2017-11-14 08:45:50<br>            q: -1.00<br>       callid: 3p9P4PgZSv<br>         cseq: 51<br>last_modified: 2017-11-14 08:44:50<br>        flags: 0<br>       cflags: 64<br>   user_agent: android_1.1.0_samsung_SM-<wbr>E500H_<wbr>7b271714c08b942aa821fc756cdd2e<wbr>890a37069e/1.1.0 (belle-sip/1.4.2)<br>       socket: udp:<a href="http://192.168.103.21:5060" target="_blank">192.168.103.21:5060</a><br>      methods: NULL<br>     instance: <urn:uuid:8369ef6e-202b-4844-<wbr>8928-492a7678c269><br>       reg_id: 0<br>    server_id: 11369<br>connection_id: -1<br>    keepalive: 1<br>    partition: 15</div>
