I have recently discovered a problem that I cannot dial internal extensions - I either get a busy tone or directed to voicemail depending on if the extension has voicemail. This was working fine, but not sure what has changed to stop this working. Today I did delete a load of extensions and setup and set of new ones. Now neither old or new can be dialled internally. Outgoing calls from each extension works fine. I'm getting the SIP registration for each phone - so they are definitely connected. The only other thing I can think of - I ran "yum -y update" which downloaded and installed a lot of stuff - I re-built the Zaptel and Network drivers after this. Your help is much appreciated Cheers Graham -------------- next part -------------- An HTML attachment was scrubbed...
