```
static val ATTR_EPDG_OVER_CELL_INTERNET: Int
```
Attribute to specify if an EPDG tunnel is setup over the cellular internet APN.
If IMS is registered through an EPDG tunnel is setup over the cellular internet APN then this bit will be set. If IMS is registered through the IMS APN, then this bit will not be set.

```
static val ATTR_REGISTRATION_TYPE_EMERGENCY: Int
```
Attribute to specify if ims registration is of type normal or emergency.
For emergency registration bit will be set. For normal registration bit will not be set. This flag is only applicable when listening to emergency IMS registration state updates via the ImsMmTelManager#registerImsEmergencyRegistrationCallback API
Value: 2
### ATTR_VIRTUAL_FOR_ANONYMOUS_EMERGENCY_CALL
Added in[API level 36.1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
