Hello, I integrated kamailio and freeswitch using the links at the bottom of the page, however, the call rejected and goes to voicemail and freeswitch generated the following messages especially I am puzzled by the following errors 2016-01-13 05:37:39.632245 [NOTICE] sofia.c:7539 Hangup sofia/internal/7632689993@10.22.52.2 [CS_ROUTING] [UNALLOCATED_NUMBER] 2016-01-13 05:37:39.632245 [INFO] mod_dptools.c:3244 Originate Failed. Cause: UNALLOCATED_NUMBER Can freeswitch use domain name since kamailio sent invite with domain but freeswitch with IP address? I am not sure if this is the issue. I looked my extensions and it looks OK but I might be wrong. Thank you again for your help Abdul ############################################################################################################################################ 2016-01-13 05:37:29.572184 [NOTICE] switch_channel.c:1055 New Channel sofia/internal/7632689991@AbdulKamailioSIP.com [e945266d-8eec-4c0e-80b4-b306f43e18df] 2016-01-13 05:37:29.572184 [INFO] mod_dialplan_xml.c:635 Processing 7632689991 <7632689991>->kb-7632689993 in context public 2016-01-13 05:37:29.572184 [NOTICE] switch_ivr.c:1861 Transfer sofia/internal/7632689991@AbdulKamailioSIP.com to XML[kb-7632689993@default] 2016-01-13 05:37:29.572184 [INFO] mod_dialplan_xml.c:635 Processing 7632689991 <7632689991>->kb-7632689993 in context default 2016-01-13 05:37:29.572184 [CRIT] mod_dptools.c:1638 WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING 2016-01-13 05:37:29.572184 [CRIT] mod_dptools.c:1638 Open /usr/local/freeswitch/conf/vars.xml and change the default_password. 2016-01-13 05:37:29.572184 [CRIT] mod_dptools.c:1638 Once changed type 'reloadxml' at the console. 2016-01-13 05:37:29.572184 [CRIT] mod_dptools.c:1638 WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING 2016-01-13 05:37:39.632245 [NOTICE] switch_channel.c:1055 New Channel sofia/internal/7632689993@10.22.52.2 [d52b6ef9-c4f6-4edf-aff9-8a8da3761788] 2016-01-13 05:37:39.632245 [NOTICE] sofia.c:7539 Hangup sofia/internal/7632689993@10.22.52.2 [CS_ROUTING] [UNALLOCATED_NUMBER] 2016-01-13 05:37:39.632245 [INFO] mod_dptools.c:3244 Originate Failed.
