Hi All, Has anyone successfully used WIP-5000 on ser? I'm trying to configure one, I can see it registering on the SIP Server, it even send out a SIP 200 Ok to the WIP-5000. Also I when I do serctl ul show <username>, I can see that it registered, but on the WIP-5000, it show Not Registered, anyone encountered this problem? Thanks in advance Regards, Ron
