Helow :) Well, i'm new on freeswitch but not on linux or network, as my first tries i was able to configure a sip gw for inbound and outbound calls, and also inbound faxes, but I'm having problems with outbound faxes. Here is my log freeswitch@internal> originate {fax_verbose=true}sofia/gateway/sip.flowroute.com/16138007319 &txfax(/path_to_fax_file) -ERR INVALID_GATEWAY 2012-02-18 22:49:11.530545 [DEBUG] switch_ivr_originate.c:1884 Parsing global variables 2012-02-18 22:49:11.530545 [DEBUG] switch_event.c:1522 Parsing variable [fax_verbose]=[true] 2012-02-18 22:49:11.530545 [ERR] mod_sofia.c:4382 Invalid Gateway 'sip.flowroute.com' 2012-02-18 22:49:11.530545 [NOTICE] mod_sofia.c:4768 Close Channel N/A [CS_NEW] 2012-02-18 22:49:11.530545 [DEBUG] switch_core_state_machine.c:494 () Running State Change CS_DESTROY 2012-02-18 22:49:11.530545 [DEBUG] switch_core_state_machine.c:504 (N/A) State DESTROY 2012-02-18 22:49:11.530545 [DEBUG] mod_sofia.c:374 N/A SOFIA DESTROY 2012-02-18 22:49:11.530545 [DEBUG] switch_core_state_machine.c:504 (N/A) State DESTROY going to sleep 2012-02-18 22:49:11.530545 [NOTICE] switch_ivr_originate.c:2459 Cannot create outgoing channel of type [sofia] cause: [INVALID_GATEWAY] 2012-02-18 22:49:11.530545 [DEBUG] switch_ivr_originate.c:3364 Originate Resulted in Error Cause: 608 [INVALID_GATEWAY] 2012-02-18 22:49:43.096288 [NOTICE] sofia_reg.c:415 Registering chiro.astraqom.ca-eico.thinktel.ca 2012-02-18 22:50:26.187940 [NOTICE] sofia_reg.c:415 Registering chiro.astraqom.ca-THINKTEL freeswitch@internal> sip.florroute.com gw works pretty good for outgoing calls but when tryng to do the fax thing it sends error. does anyone has an idea?
