Communication between a first wireless terminal and a second wireless terminal, where the first wireless terminal may have at least one feature that the second wireless terminal may not have, is established. In one specific example, the at least one feature may relate to a video call capability. Thus, for example, the second wireless terminal may not be capable of handling a video call. In that case, the communication between the first wireless terminal and the second wireless terminal may be downgraded to a voice communication. |
