To upgrade from OpenSIPS 1.4 to 1.7

1. Make sure the latest Enswitch fixes are installed.
2. Do:
   • cd /etc/opensips
   • cp opensips.cfg opensips.cfg-1.4
3. Make the following changes to opensips.cfg:
   • Add 'loadmodule "signaling.so"' just above the other loadmodule lines.
   • Remove 'loadmodule "xlog.so"'.
   • Change '$avp(i:42)' to '$avp(42)' in the 'modparam( "nathelper|registrar", "received_avp", "$avp(i:42)" )' line.
   • Remove 'modparam( "registrar", "append_branches", 1 )'.
   • Remove 'modparam( "rr", "enable_full_lr", 1 )'.
   • Remove 'modparam( "usrloc", "fetch_rows", 500 )'.
4. In /opt/enswitch/current/bin/enswitch_install, change $ser_version to '1.7.2' and $ser_dir to '1.7.2-tls'.
5. Do:
   • enswitch sql "update version set table_version=1006 where table_name='location'"
   • enswitch sql "update version set table_version=7 where table_name='phones'"
   • enswitch install -u opensips
6. Do "ps -ef | grep opensips" and check that OpenSIPS is running and that all the processes started at the expected time.
7. Test calls.

Should you need to revert, the 1.4 database table versions are 1004 for location and 6 for phones.
