WHen I call out the usual ring tone has gone away. It is just silence until the called party answers. Any ideas on how to get the ring tone back?

I've had this before, just can't remember exactly what it was. I have got a feeling it was something to do with early media and /or receiving both a 183 Session progress and a 180 Ringing.

I'll have a look back through my notes, if I find anything I'll post back. Hopefully someone else will get you a better answer in the meantime.
