Abstract: This disclosure provides techniques to support Internet Protocol (IP) Multimedia Subsystem (IMS) virtual clients (14) in a multi-operator environment. More specifically, the present disclosure provides new subscription types that can be utilized for serving IMS clients in enterprise communication systems. The improved type of subscription enables compatible IMS service providers (16, 18) to comprehend an enterprise-generated domain name in SIP sessions, where the enterprise-generated domain name is different than the explicit domain name corresponding to the IMS service provider. This ensures that an enterprise IMS node/client can obtain an IMS Public User Identity (IMPU/IMP) and use the domain name for a particular IMS service provider that was obtained by the enterprise to refer to the IMS service provider used for handling the session for the IMPU.
