A router associated with a private branch exchange, can comprise a cellular modem to facilitate radio communication with a cellular network. The router can also perform operations associated with converting wireline signal data to cellular signal data and cellular signal data to wireline signal. A mobility network can also convert wireline signal data to cellular signal data via a virtual Internet gateway that can be used to encrypt or decrypt a voice signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Facilitation of session initiation protocol trunking","description":"Session initiation protocol (SIP) trunking can be facilitated via a mobility network comprising a router and a virtual internet gateway.
