A standby routing fault-tolerance unit obtains a plurality of inbound routing packets of a first routing processing unit by using a forwarding unit and an active database unit. The first routing processing unit is a routing processing unit corresponding to an active routing fault-tolerance unit. The standby routing fault-tolerance unit sends the plurality of inbound routing packets of the first routing processing unit to a second routing processing unit. The second routing processing unit is a routing processing unit corresponding to the standby routing fault-tolerance unit.

A processing system of an edge exchange point including at least one processor may receive, from a cloud service provider a request to allocate a first tag to communications between the cloud service provider and a first telecommunication network, transmit an acceptance of the request to allocate the first tag to the communications between the cloud service provider and the first telecommunication network, obtaining a first packet containing the first tag from the cloud service provider, and transmit the first packet to the first telecommunication network in accordance with the first tag.

Novel tools and techniques for providing an in-line AI virtual assistant are provided. A system includes a session border controller coupled to an end-user device, and a session initiation protocol stack. The session initiation protocol stack includes a processor, and non-transitory computer readable media comprising instructions executable by the processor to: receive, from the session border controller, a call invite request; provision, via the AI virtual assistant service, an AI virtual assistant instance in response to the call invite request; and join the AI virtual assistant instance to a call with the end-user device.

The present disclosure relates to a routing control method, a system, and a BGP Peer. The method of the present disclosure can be executed by a first BGP Peer, including: receiving information of adding a new VPN route sent from a second BGP Peer, wherein the information of adding the new VPN route comprises: the new VPN route and an identifier of a first VPN instance; determining whether a number of VPN routes corresponding to the identifier of the first VPN instance reaches or exceeds a limit value after adding the new VPN route; and sending first instruction information to the second BGP Peer to instruct the second BGP Peer, in a case that the number of VPN routes corresponding to the identifier of the first VPN instance reaches or exceeds the limit value, wherein the first BGP Peer is an iBGP Peer inside a first AS.

This application discloses a communication method and apparatus, to improve transmission efficiency of a control plane message of a terminal according to a control and provisioning of wireless access points protocol. In this application, a control request message of a terminal may be transmitted between a first communication apparatus and a second communication apparatus through a target channel. Because the target channel supports concurrency of a plurality of messages, transmission efficiency of the control request message of the terminal can be improved.

Systems and techniques are provided for voice calling with a connected device that does not include a SIM card or telephone port. Outgoing audio data may be received at an embedded browser running on a connected device, may be sent using Web Real Time Communications (WebRTC) from the embedded browser to an integration layer running within the embedded browser, and may be sent from the integration layer to a border controller for a voice call carrier over a Session Initiation Protocol (SIP) connection according to Secure Real Time Transport Protocol (SRTP). Incoming audio data may be received at the integration layer from the border controller for the voice call carrier over the SIP connection according to SRTP, may be sent using WebRTC from the integration layer to the embedded browser, and may be sent from the embedded browser to an audio output of the connected device which may output audio.

A first SBC establishes a first media session between a transferor and a transferee. A second SBC establishes a second media session between the transferor and a transfer target. The first SBC receives a REFER message initiated by the transferor and determines that a dialog ID in the REFER message does not correspond to a media session currently being handled by the first SBC. The first SBC sends a SIP INVITE message to a plurality of SBCs, including the second SBC, that are in a load sharing group with the first SBC. The SIP INVITE message includes the dialog ID associated with the second media session, which triggers the second SBC to re-use the second media session to establish a media session between the transferee and the transfer target.

In a voice-over-IP communications network, call data records include dynamically assigned IP signaling addresses such as IPv6 signaling addresses used in provisioning communications sessions. Those dynamically assigned IP signaling addresses are computed from customer site identification codes using a reversible algorithm. The algorithm can then be reversed to compute a customer site identification code from an IP signaling address contained in a call data record, allowing the communications network provider to perform quality monitoring and diagnostics based on call data records.

A system for establishing a network communication between two or more users receives a request to establish a call between an endpoint device associated with a user and user equipment (UE) associated with a client. The system determines that the endpoint device is available for a call by querying a network node configured to route calls to the endpoint device. The system routes a first call to the endpoint device. The system routes a second call to the UE. The system establishes a call between the user and the client by merging the first call and the second call.
