2. If the calling user is a non-VoLTE user, or the calling terminal does not have the ability to play the video color ring back tone, or the calling terminal cannot apply for enough network bandwidth resources to play the video color ring back tone at the ringing stage, the system will play the audio color ring back tone for the called user who has subscribed to the video color ring back tone service regardless of whether the calling party initiates an audio call or a video call.

Other considerations:
1, conditions of use
When a VoLTE customer of China Mobile makes a call to a customer who has subscribed to the VoLTE video color ring back tone function by using a terminal that supports playing video color ring back tone, the calling customer can see the called customer's video color ring back tone whether it is an audio call or a video call under the condition that the current bandwidth resources of the network are sufficient.
If the calling user is a non-VoLTE user, or the calling terminal does not have the ability to play video color ring back tones, or the calling terminal cannot apply for enough network bandwidth resources to play video color ring back tones during the ringing stage, the system will play the called user's audio color ring back tones for the called user regardless of whether the calling party initiates an audio or video call to the called user who has subscribed to the video color ring back tones service.
Video CRBT service supports China Mobile's inter-provincial roaming, but temporarily does not support Hong Kong, Macao and Taiwan and international roaming.
2. The difference between video color ring tones and audio (or ordinary) color ring tones.
When a customer opens a video color ring service, when a friend calls the customer, he will have the opportunity to see a video set by the customer, while the audio (or ordinary) color ring is just music or songs. That is, video CRBT is sound+picture, while audio (or ordinary) is just sound.
3. Conditions for watching video color ring tones
(1) Calling customer (caller):
The mobile phone supports video color ring back tone playback and upgrades to the latest system.
Turn on VoLTE HD voice function.
