Can not make out bound calls on UC520 8.0

Unanswered Question
Dec 15th, 2009

We are having some issues with UC520.  Various IP SPA508g phones will not allow outside calls on PRI.  The phones will run fine then all the sudden no go.  You press 9 dial the number and you get dead air.  If you reboot the phone that seems to fix the problem for a short while.  Then we got issues the VM pilot DN3099 same deal some phones go through to VM some do not.

I am getting tired of rebooting phones.

I have this problem too.

I don't know of any issues like you are describing.  Would you mind opening a TAC case?  I think that would be the quickest way to resolve this issue.
