The present disclosure provides a method for managing voice calls and gateway device. A gateway device according to the embodiment of the present disclosure includes a voice call module for being connected with a landline device and/or a mobile voice device and configured to provide a calling out service to the landline device and/or the mobile voice device; a cellular session initiation protocol (SIP) client module for being connected with a cellular network and configured to process voice signalling in a cellular network; an IP network SIP client module for being connected with an IP network and configured to process voice signalling in an IP network; and a voice call selection module configured to, when receiving a calling out from the voice call module, select either the cellular SIP client module or the IP network SIP client module for the calling out.

Gateway device and method for managing voice calls

The present disclosure provides a communication node and method for routing data packets for a client device. The communication node includes: one or more processors; a memory coupled to the processors; and computer program instructions stored in the memory, which, when executed by the processors, perform actions of: obtaining, from a downstream communication node, NAT routing information for a data packet communicated between the client device and an external node through at least the communication node and the downstream communication node; and performing NAT on a subsequent data packet to be communicated between the client device and the external node based on the NAT routing information.
