A TAS may fork an incoming invite for packet switched connectivity to all user devices of a same user account registered for parallel forking. When receiving a SIP client failure response from one of the user device, TAS will determine whether a SIP 18X provisional response is received prior to the client failure response from the same user device. If such a provisional response is not received prior to the client failure response, TAS will not terminate the invite forking."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhanced telephony application server session management","description":"A solution for an enhanced telephony application server session management is described herein.
