Just recently got my first voicemail and unfortunately I haven't been able to access it. A little bit of googling showed that *98 should allow me to access VM from the softphone using the VOIP key but that doesn't work (just hear a harsh tone for ~ 30 seconds before it disconnects). I tried modifying some settings in the OBIHAI system management based on a post on the obihai forums. That hasn't worked for me either ( the poster suggested disabling auto provisioning and then modifying the digimap for SP1 but the change reverts back to default after reebooting the obihai). I was finally able to access my VM using the regional code but that took forever and is most definitely not convenient - especially for the wife.
Any help is greatly appreciated, thanks!
