I have installed the following rpms:
selintra-sail-2.1.14-507.noarch.rpm
smeserver-asterisk-1.2.20-8.i686.rpm
smeserver-asterisk-zappri-MPP-1.2.13-1.i686.rpm
on my server and my mates server in the UK and I am having a problem with a Sail2Sail sibling. I have created the sibling trunk but in server-manager it doesn't show as connected on either server

I can call the extensions of the UK server OK, but my mate can't call my server

He gets a message saying "Please hang up and try again" from his server, we assume that it's from his server because it's that posh English guy

I have followed the docs to add the sibling on both servers, my exts are 50xx and his are 51xx and I have added this route on his server _50xx and this route on mine _51xx I am basically struggling now and would welcome any ideas and suggestions.
Regards,
Del
