Hello I am trying to configure my Cisco 8851 devices to allow for 2 extensions to be registered at once. One Extension 5806 is a personal extension that only this phone will have access to whereas 5000 is a HelpDesk Extension that multiple phones need to be able to receive calls to. Whenever I try and add the additional line I get SIP Registration errors due to bad authentication. The username and passwords are set properly for both accounts.
Any help would be greatly appreciated.
