Abstract: A system that incorporates teachings of the present disclosure may include, for example, receiving a session initiation protocol (SIP) subscribe message over a primary call leg requesting outdial event notification on a secondary call leg. Receiving of the call is responsive to a unified messaging system placing a call outside of its local access and transport area. A call is placed on the secondary call leg responsive to receiving outdial information on the primary call leg. Alternative outdial information directed to the calling party is received responsive to the call on the secondary leg being unanswered. Another call is placed on the secondary leg responsive to receiving the alternative outdial information without requiring receipt of another SIP subscribe message over the primary call leg. A calling card server performs SIP messaging associated with one of the SIP notify message or the SIP subscribe message. Other embodiments are disclosed.
