These features are MMTel specific.

Feature What it does

a logical representation of supplementary service data as a group of POJO objects. It allows MMTel services/features to execute independently of any concrete schema for the supplementary service data. Therefore it can be loaded from the HSS or the HLR using the MMTel-Services XML schema or 3GPP MAP ASN.1 schema.

connects the IMPU acquired from the subscriber registration to the existing ACI for the session transfer

checks if the subscriber has the STOD service provisioned

handles the transfer request and route it to the previous bound session

intercepts the transfer INVITE routed by the MMTelStodTriggerAnchor feature and connects the existing called led to the new calling leg and releases the previous calling leg

enables a party involved in a communication to transfer their role in that communication to a third party

adds the geo-local value to the Tel URI phone-context parameter for local numbers that should not be translated to international format.
