I'm having a problem with failover. I have the call_timeout set to 15 seconds which results in a landline ringing 4 rings, and INSTANTLY after the 4th ring fails over to the failover destination. However, if the number being dialed is a cell phone I've had one of two things happen: it will either ring and ring until voicemail, or what seems to happening now (I'm not sure what setting caused this) it will rings twice and there will be dead air and eventually the calling side will time out and fail. timeout=15 desk phone: 4 rings -> failover sprint mobile: 5 rings -> voicemail verizon mobile: 5 rings -> voicemail <section name="dialplan" description=""> <context name="public"> <extension name="did"> <condition field="destination_number" expression="^($did)$"> <!-- set the caller id --> <action application="set" data="effective_caller_id_name=Bob Smith"/> <action application="set" data="effective_caller_id_number=8005551234"/> <!-- stops processing the dialplan after call is bridged --> <!-- <action application="set" data="hangup_after_bridge=true"/> --> <!-- this is needed to allow call_timeout to work after bridging to a gateway --> <action application="set" data="ignore_early_media=true"/> <!-- continue to process the dialplan after failure --> <action application="set" data="continue_on_fail=NO_ANSWER"/> <action application="set" data="continue_on_fail=true"/> <!-- <action application="set" data="continue_on_fail=NORMAL_TEMPORARY_FAILURE,TIMEOUT,NO_ROUTE_DESTINATION,NO_ANSWER"/> --> <!-- try the client shop --> <action application="set" data="call_timeout=15"/> <action application="bridge" data="sofia/vitelity/<number to try>@<carrier>"/> <!-- failover destination --> <action application="bridge" data="sofia/vitelity/$0@<failover dest>"/> </condition> </extension> </context> </section> call to desk: 2008-10-15 15:47:13 [NOTICE] switch_channel.c:534 switch_channel_set_name() New Channel sofia/vitelity/<caller>@<carrier> [1022c19a-9af2-11dd-bf67-89c26635687a] 2008-10-15 15:47:13 [INFO] mod_dialplan_xml.c:222 dialplan_hunt() Processing <caller>->4073921320@public 2008-10-15 15:47:13 [NOTICE] switch_channel.c:534 switch_channel_set_name() New Channel sofia/vitelity/4078023342@<carrier> [1026f4ae-9af2-11dd-bf67-89c26635687a] 2008-10-15 15:47:14 [NOTICE] sofia.c:2167 sofia_handle_sip_i_state() Ring-Ready sofia/vitelity/4078023342@<carrier>! 2008-10-15 15:47:14 [NOTICE] mod_sofia.c:1058 sofia_receive_message() Ring-Ready sofia/vitelity/<caller>@<carrier>! 2008-10-15 15:47:14 [NOTICE] switch_ivr_originate.c:1148 switch_ivr_originate() Ring Ready sofia/vitelity/<caller>@<carrier>! 2008-10-15 15:47:28 [NOTICE] switch_ivr_originate.c:1277 switch_ivr_originate() Hangup sofia/vitelity/4078023342@<carrier> [CS_CONSUME_MEDIA] [NO_ANSWER] 2008-10-15 15:47:28 [INFO] mod_dptools.c:1789 audio_bridge_function() Originate Failed.
