I've recently installed a vanilla OpenSER v1.3.0 (a new install) and I'm trying to set up permanent user locations using openserctl as I have some devices that won't register on their own. I am currently running without a database. When trying to add a user using the command line "openserctl ul add 100 sip:192.168.1.40" I get the error: ERROR: 400; check if you use aliases in OpenSER. Can someone please give me some pointers on what to try? Thanks Ashley I've modified the openserctlrc as follows: # $Id: openserctlrc,v 1.2 2006/07/05 19:37:20 miconda Exp $ # # openser control tool resource file # # here you can set variables used in the openserctl ## your SIP domain SIP_DOMAIN=openser.development.newvoicemedia.com ## database type: MYSQL or PGSQL, by defaulte none is loaded # DBENGINE=MYSQL ## database host # DBHOST=localhost ## database name # DBNAME=openser ## database read/write user # DBRWUSER=openser ## database read only user # DBROUSER=openserro ## password for database read only user # DBROPW=openserro ## database super user # DBROOTUSER="root" ## type of aliases used: DB - database aliases; UL - usrloc aliases ## - default: none ALIASES_TYPE=""UL ## control engine: FIFO or UNIXSOCK ## - default FIFO # CTLENGINE="FIFO" ## path to FIFO file # OSER_FIFO="FIFO" ## check ACL names; default on (1); off (0) # VERIFY_ACL=1 ## ACL names - if VERIFY_ACL is set, only the ACL names from below list ## are accepted # ACL_GROUPS="local ld int voicemail free-pstn" ## verbose - debug purposes - default '0' VERBOSE=1 Free Phone: 0800 280 2888 Tel: +44 (0)1256 892020 Fax: +44 (0)1256 892200 Registered Office: NewVoiceMedia Ltd, Laverstoke Grange, Laverstoke, Whitchurch, Hants, RG28 7PF NewVoiceMedia Registered in England No: 3602868
