Hi Mr X
Thanks for the reply, below is the extract from the systems log file of an attempted call in - it's passed through the correct mobile number that I was using to test, just the call doesnt actually go any where. BTW I made a few errors on the IP addresses in my first post, now updated.
I'm presuming the 404 messages below are playing a part in it failing to work.
