Abstract
Methods, systems, and devices are described for indicating, by a multimode access point, an availability of a service on a first RAT to a mobile device via a second RAT. The multimode access point may determine whether a service is available from a base station on the first RAT, e.g., a VoLTE service from a LTE base station. The multimode access point may send an indication to the mobile device of the available services. The mobile device may configure a voice call session based on the available services and initiate the voice call session accordingly.
