He all, I'm still quite new to FS, so sorry if this is just a stupid question. I'm trying to setup a queue with mod_fifo. Really simple, just with two phones. Idea is that people call a number, hear moh and the two phones are ringing. If picked up, the call is bridged. So I tried this: fifo.con.xml <configuration name="fifo.conf" description="FIFO Configuration"> <fifos> <fifo name="fifo_kunden@192.168.1.93" importance="0"> <member timeout="120" simo="1" lag="5">{call_timeout=30,fifo_member_wait=nowait}user/10@192.168.1.93</member> <member timeout="120" simo="1" lag="5">{call_timeout=30,fifo_member_wait=nowait}user/15@192.168.1.93</member> </fifo> </fifos> </configuration> In my public.xml dialplan I put: <extension name="Local_Extension"> <condition field="destination_number" expression="^(4930XXXXXXXX)$"> <action application="transfer" data="fifo_kunden"/> </condition> </extension> <extension name="fifo_kunden"> <condition field="destination_number" expression="^fifo_kunden$"> <action application="answer"/> <action application="fifo" data="fifo_kunden@192.168.1.93 in undef $${base_dir}/sounds/music/8000/ponce-preludio-in-e-major.wav"/> </condition> </extension> A caller now hears the music, but the phones aren't ringing (and there are no error messages about this). I changed the @192.168.1.93 from @$${domain}, cause FS tried to call for example 12@a different ip then my phones are registered. This is, because I've got two ips. One from my provider, receiving and sending calls there, and 192.168.1.93, where my phones are registered. Before I changed the @setting, FS gave me an error that the phone 12@my-provider-ip is absent, which is true. So I thought I just have to change the domain setting. What I'm missing here? Thanks, Georg
