So after disappearing up my own backside I realised that my issue (and it most likely isn't really an issue) when testing inbound routes to extensions with UK ringback, its working when I first test after making a change but if I drop the call from the remote end after, say, 5 rings and then try immediately again, the inbound call rings the handset fine, but the ringback tone doesn't get produced to the remote caller.

If I wait a period of time and try again it works. I thought maybe it was my mobile carrier that Im testing the call with, however I tried a call from another domain on the tenant, and that rang, then I tired immediately with my mobile again and the handset rang but not ringback.

Compounded to this, if I add the uk-ring to 2 or more inbounds to extention it stops working completely

Any ideas? Obviously a timeout somewhere?

Apart from Ring groups, I don't normally have to set uk-ring anywhere, it is just set in the switch variables, see screenshot:

Hi Adrian

Yes defaults set to uk like yours above. Something strange on this system, don't know if you remember but I ended up having to copy my uk voices into the us folder as Id get 90% uk voices and then it would drop a us one in randomly.

Hi Tim, Yes we suffered with the odd announcement reverting to US. Probably on voicemail, I can't exactly remember now. I solved it with the following settings:
In /etc/freeswitch/languages/en modify en.xml for Rachel
Code:
<language name="en" say-module="en" sound-prefix="$${sounds_dir}/en/gb/rachael" tts-engine="cepstral" tts-voice="rachael">


In Advanced->Variables:
Code:
default_country = GB
default_dialect = gb
default_voice = rachael
sound_prefix = $${sounds_dir}/en/gb/rachael

From my notes, I think that is all we had to do.

EDIT: Just remembered, there are a couple of .wav files that are not in the rachael sounds pack, I created them by cutting and splicing from other rachael prompts:

vm-no_answer_no_vm.wav
vm-message_from.wav

Cant work it out, something in an xml file maybe that ill have to sift, Ive gone with ring groups for the ddi to get the install done tomorrow. I can choose uk-ring from the gui for the ring group. Ive created one for each inbound and stuck the single extension in it. Not pretty but works.
