Method, storage medium and device for stacking and forwarding call service of access device

Abstract

The invention discloses a method,storage medium and device for stacking and forwarding call service of access device. The access device comprises a main access device and at least two stacked access devices. The method comprises the following steps: according to a current call request, querying a local call routing table and obtaining a stack number of a target access device corresponding to the call request according to the call routing table; If it is judged that the access device corresponding to the stack number belongs to the stack access device, sending the call request to the stack access device so that the stack access device performs corresponding call service processing; If it is judged that the access device corresponding to the stack number belongs to the main access device, sending the call request to the main access device for processing so that the main access device performs corresponding call service processing. The invention realizes the smooth expansion of the numberof user ports when the access equipment is stacked and the internal user calling service of the access equipment without the participation of an external system.

Description

technical field [0001] The invention belongs to the field of softswitch communication, and in particular relates to a method, a storage medium and a device for stacking and forwarding call services of an access device. Background technique [0002] An integrated access device (IAD, Integrated Access Device) is an access device that can simultaneously deliver traditional PSTN voice services, packet voice services, and data services on a single WAN link (via a LAN port). Suitable for small businesses and home users, it can provide users with traditional PSTN voice services, VoIP voice services and data services at the same time. The existing IAD has a limited number of user ports. When it is necessary to expand the user port capacity of the IAD, it is possible to expand the number of user ports by configuring multiple user access modules inside the AG by using an access gateway (AG) device; or configuring Multiple IADs implement expansion of user ports. Since the access gate...

AI Technical Summary

Problems solved by technology

Since the access gateway device is a central office device that provides more traditional telephone ports, complex installation conditions and supporting facilities (such as setting distribution frames in the computer room, etc.) are required when switching to the access gateway device. The conditions are harsh, and it is impossible to easily and quickly expand the capacity of the user port

When configuring multiple IADs, it is necessary to increase the access address and routing addressing configuration for these newly added IADs in the external system; as the number of configured IADs increases, the routing configuration data in the external system increases geometrically, resulting in External system configuration becomes complicated

At the same time, since the call service between multiple IADs requires the participation of the external system, when the external system fails and the communication is interrupted, the internal call service between each IAD is paralyzed
