Hi, I posted earlier about 'sip show registry' not showing any trunks and there seeming to be no attempt by one of my systems to register with our service provider. Following some notes elsewhere I ran 'myisamchk *.MYI' on the mysql database and it came up with an error in sip.MYI, which I repaired. Unfortunately, still no registration so I backed up the database, deleted the trunk details in the database using phpmyadmin and then re-made it. Still no joy. I am hoping I am close to solving this without a complete reinstall ad would appreciate any advice on sensible (and no so sensible!) things to try to fix SIP trunk registration. Thanks Nigel Kendrick
