When running Freeswitch as service called teoswitch as user teoswitch I cannot make calls through the Sangoma PRI or analog cards using wanpipe driver. I have added a file called 30-wanpipe.rules to /etc/udev/rules.d and rebooted the server. cat 30-wanpipe.rules # /etc/udev/rules.d/30-wanpipe.rules SUBSYSTEM=="wptdm", OWNER="teoswitch", GROUP="teoswitch", MODE="0660" SUBSYSTEM=="wanpipe", OWNER="teoswitch", GROUP="teoswitch", MODE="0660" Freeswitch log: Dialplan: sofia/internal/5410@192.168.72.45:5060 parsing [default->SangomaPRI] continue=false Dialplan: sofia/internal/5410@192.168.72.45:5060 Regex (PASS) [SangomaPRI] destination_number(93491045) =~ /^9(\d+)$/ break=on-false Dialplan: sofia/internal/5410@192.168.72.45:5060 Action set(effective_caller_id_number=425740${caller_id_number}) Dialplan: sofia/internal/5410@192.168.72.45:5060 Action bridge(openzap/smg_prid/a/3491045@g1) 2010-02-25 16:51:11.328635 [DEBUG] switch_core_state_machine.c:122 (sofia/internal/5410@192.168.72.45:5060) State Change CS_ROUTING -> CS_EXECUTE 2010-02-25 16:51:11.328635 [DEBUG] switch_core_session.c:1019 Send signal sofia/internal/5410@192.168.72.45:5060 [BREAK] 2010-02-25 16:51:11.328635 [DEBUG] switch_core_state_machine.c:341 (sofia/internal/5410@192.168.72.45:5060) State ROUTING going to sleep 2010-02-25 16:51:11.328635 [DEBUG] switch_core_state_machine.c:314 (sofia/internal/5410@192.168.72.45:5060) Running State Change CS_EXECUTE 2010-02-25 16:51:11.328635 [DEBUG] switch_core_state_machine.c:348 (sofia/internal/5410@192.168.72.45:5060) State EXECUTE 2010-02-25 16:51:11.328635 [DEBUG] mod_sofia.c:181 sofia/internal/5410@192.168.72.45:5060 SOFIA EXECUTE 2010-02-25 16:51:11.328635 [DEBUG] switch_core_state_machine.c:159 sofia/internal/5410@192.168.72.45:5060 Standard EXECUTE EXECUTE sofia/internal/5410@192.168.72.45:5060 set(effective_caller_id_number=4257405410) 2010-02-25 16:51:11.328635 [DEBUG] mod_dptools.c:811 sofia/internal/5410@192.168.72.45:5060 SET [effective_caller_id_number]=[4257405410] EXECUTE sofia/internal/5410@192.168.72.45:5060 bridge(openzap/smg_prid/a/3491045@g1) 2010-02-25 16:51:11.339637 [ERR] switch_core_session.c:357 Could not locate channel type openzap 2010-02-25 16:51:11.339637 [ERR] switch_ivr_originate.c:2411 Cannot create outgoing channel of type [openzap] cause: [CHAN_NOT_IMPLEMENTED] 2010-02-25 16:51:11.339637 [DEBUG] switch_ivr_originate.c:3209 Originate Resulted in Error Cause: 66 [CHAN_NOT_IMPLEMENTED] 2010-02-25 16:51:11.339637 [INFO] mod_dptools.c:2346 Originate Failed.
