Abstract
In one embodiment, an IMS network node is operable, responsive to receiving a SIP INVITE request from an enterprise user to initiate origination of an outgoing cellular call to a called party, for establishing a first call leg to the enterprise user by sending a SIP INVITE message back to the enterprise user. The IMS network node includes functionality for establishing a second call leg to the called party. The first and second call legs are patched to establish an end-to-end communications path between the enterprise user and the called party, wherein an enterprise address instead of a non-enterprise address of the enterprise user is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.
