Landslide: MME Nodal - VoLTE - Why second default bearer is not coming up even if all the configuration has been set up?

Environment/Versions
  • Landslide
  • MME Nodal
    • 2 Default Bearers (1st for Default access, 2nd for IMS Signaling)
    • VoLTE
Answer

When more than 1 default bearer is used the PDN Connect Delay should be set to a value different than zero. This is because emulated UE needs to be sure the first default bearer establishment procedure has been started before a subsequent bearer could be set up.
