FS or anything else, opposite of profile configurations, arbitrarily, changes sip port 5060 to 10037! this is my sip profile: freeswitch@internal> sofia status Name Type Data State ================================================================================================= 89.165.7.58 alias sipinterface_2 ALIASED voicemail_1 alias sipinterface_2 ALIASED voicemail_2 alias sipinterface_2 ALIASED sipinterface_2 profile sip:mod_sofia@192.168.2.73:5070 RUNNING (0) sipinterface_5 profile sip:mod_sofia@192.168.2.73:10037 RUNNING (0) sipinterface_5::trunk_3 gateway sip:TCAPI_User@192.168.2.10 NOREG sipinterface_3 profile sip:mod_sofia@192.168.2.73:5080 RUNNING (0) ================================================================================================= 3 profiles 3 aliases Also, in a few weeks ago, i saw that sip crawlers with high sip registration requests can meddle on FS SQLite db reactions belongs to sip interfaces! In that event, i was forced to delete sipinterface_1 identified with SQLite DB and define new interface named sipinterface_5 with port 5060. This paragraph is just one report although everyone knows FS is a great man! I will send you XML config file, if it's needed! Good luck,
