We have a number of Nokia E series phones that we're trying to get to work with a 1231 access point for SIP. On occasions it will associate but generally when we try to join the phone to the SSID it will crash and reboot. The AP is running c1200-k9w7-mx.123-8.JA. It's configured with both voice and data VLANs. Is this a know issue with Aironets? Is there any way I can figure out what?s going on?
Any help much appreciated.
