VoicePulse, freepbx upgrade , can not register

freepbx and trixbox ce.

i upgraded
core module from to
queues from to

after doing so we had major problems.
1- when dial out: 'all circuits are busy’
2- at CLI i: 'sip show registry ’ showed us un-registered with our service provider- Voice Pulse.
3- we are using the latest Voce Pulse module.

to solve the problem I restored our ‘System configuration’ from a backup done early today.
I had tried rebooting before the restore, which did not fix the problem.

Has anyone else had this problem?
