The SDP record will look like this:

Service Name: Dialup Networking
Service RecHandle: 0x10006
Service Class ID List:
  "Dialup Networking" (0x1103)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 6
Profile Descriptor List:
  "Dialup Networking" (0x1103)
    Version: 0x0100

If you don't have that record, either the phone can't do DUN, or there's
something on the phone that's not enabled to make DUN show up.
