An enterprise's boss is enlightened, knowledgeable, and well-managed. From selling lunch boxes to today's three branches in China, he is very cautious in every aspect, to save business costs. The call between two branches and the Headquarters uses the traditional PSTN Telephone Network. The Annual Long call fee occupies a large cost for the company. One day, I was a little annoyed to be in charge of network management. I said: You see XXX company used its enterprise network to get an IP address.

Delete disk partitions by mistake in ESXi Because you are not familiar with ESXi commands and are careless, you accidentally delete the partitions of the ESXi operating system. The operation procedure is as follows: Obtain disk device information: [Root @ localhost: ~] Fdisk-l [Root @ localhost: ~] Fdisk-l **** ** The fdisk command is deprecated: fdisk does not handle GPT partitions. Please use partedUtil*** Found valid GPT with protective MBR; using GPT Disk/dev/disks/t10.

We also talked about the SIP Protocol and related SIP protocol stack. In this paper, we propose a software structure and design implementation scheme of the software telephone based on the SIP protocol. this solution is based on the embedded Windows CE platform. The middleware uses the Open-Source SIP protocol stack oSIP/eXosip, through protocol stack transplantation and application development on the protocol stack, the SIP software phone is implemented. the test results show that the software

The hard drive using the SATA (serial ATA) interface is also called a serial drive. In the 2001, the Serial ATA Commission, made up of Intel, APT, Dell, IBM, Seagate and Serial, officially established the ATA 1.0 specification, and in 2002, although serial ATA related equipment was not officially listed, serial The

The Serial ATA 1.0 specification was formally established in 2001 by the Serial ATA Board of Intel, APT, Dell, IBM, Seagate, and th

hard Disk Interface The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all hard drive integrated controller design belongs

If you add a disk that has been installed with an operating system (such as a disk that has been installed with a Windows system) to the vSphere Client, you cannot directly add a drive, you need to log on to the ESXi console through SSH.Obtain disk device information:# Esxcfg-scsidevs-lMpx.

The demand for remote access is constantly increasing, and new technologies are also emerging. Even if one of eicon ums and VoIP servers is used, we will mainly introduce UMS (Unified Message Service ), this section describes the DIVA server card and Voice Gateway. As the world's leader in the remote access market, EICON is particularly outstanding in the ISDN field. It has a full range of isdn diva pc customer card/Server card, ISDN box MODEM and ISD

Go to your own blog early, and save it for future blocking. Single radio voice call continuity (srvcc) srvcc is an LTE functionality that allows a VoIP/IMS call in the LTE packet domain to be moved to a legacy voice domain (GSM/UMTS or CDMA 1X ). consider a case where a new LTE network operator wants to move voice services to VOIP over IMS in conjunction with the deployment of an LTE access network. in the

SCSI Small Computer System Interface (Small Computer System Interface), which was first developed at 1979, is an interface technology developed for minicomputers. However, with the development of computer technology, now it is completely transplanted to a normal PC. ATA (at embedded interface) The purpose of this interface is to directly connect the bus in the at computer manufactured in 1984 with the driver and controller that are combined. The "at"

number is the primary flag, representing the number of slices in the normal IDE hard drive. For example, "2" means that there are 2 platters in the drive. In Seagate's SCSI drive, the primary ID is the speed of the hard drive. The second number is the secondary flag, which is the auxiliary flag for the hard drive. The secondary flag is valid only if the primary flag is the same or invalid. It is generally used to represent the algebra of hard disks, the larger the number of tablesThe higher the

characteristics of strong, for its other types of hard disk can not replace the status. Development process Early IDE interfaces have two transport modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although DMA mode system resources are low, they require additional drivers or settings and are therefore less acceptable. Later, in the case of higher speed requirements, the DMA mode is more efficient, the operating system starts to support directly, and the ma

Basic SIP Application As one of the main VOIP communication protocols, the SIP protocol is simple, flexible, and open, and is gradually dominant in the VOIP communication field. The main methods used for SIP Communication include SIP terminals, proxy/targeted servers, location servers, and PSTN gateways. Currently, the latest standard of the SIP protocol is RFC3261. Major network equipment providers can cu
