at least one processor,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to

responsive to receipt of a message containing no media content and indicating one or more supported media types by a group, cross-check the indicated supported media types by the group with capabilities of the apparatus to find out whether or not the indicated one or more supported media types by the group are supported by the apparatus; and

show the message to a user when all indicated supported media types are supported by the apparatus capabilities,

wherein supported media types by the group are group-specific supported media types, based on group definitions and may contain on or more media types that are not supported by an apparatus a group member is using.

11. The apparatus of claim 10 , wherein the at least one memory and the computer program code are also configured to, with the at least one processor, cause the apparatus at least to:

filter from the message any indicated supported media type that is not supported by the user equipment capabilities.

12. A method, comprising:

receiving, by an apparatus supporting group communication, a message containing no media content and indicating one or more supported media types by a group;

cross-checking, by the apparatus in response to the message, indicated said at least one supported media type with group-specific media types defined to be usable by the group to find out whether or not the indicated at least one supported media type can be found in the group-specific media types defined to be usable by the group; and

deciding, by the apparatus, how to continue based on the cross-checking.

13. The method of claim 12 , wherein

the cross-checking includes cross-checking the indicated supported media types with defined supported media types and the method further comprises:

adding, by the apparatus, to the message any defined supported media type that was originally missing from the message as the indicated supported media type.

14. The method of claim 12 , wherein

the cross-checking includes cross-checking the indicated supported media types with defined supported media types and the method further comprises:

filtering, by the apparatus, from the message any indicated supported media type that is not included in the defined supported media type for the group.

15. The method of claim 12 , wherein

the cross-checking includes cross-checking the indicated supported media types with allowable media types of a group member and the method further comprises:

filtering, by the apparatus, from the message any indicated supported media type that is not included in the allowable media types of the group member.

16. The method of claim 12 , wherein

the cross-checking includes cross-checking the indicated supported media types with group member capabilities of a group member and the method further comprises:
