hello sir


In most cases, you will probably need to get another ATA or VoIP hardware device, one that is supplied by the new VoIP provider themselves.  Even though some providers use similar devices, they may have proprietary software (configuration files) on them which cannot easily be changed unless they you can gain access to the Advanced Settings pages of the ATA.  Some providers allow a BOYD service which might be an unlocked ATA where you have access to the settings and parameters of the device.  This would be an advantage for both a person interested in the more technical adjustments available on the ATA and being able to provide new settings to connect to a new provider.

thanks

Hello john,

Shadow password packages are used for security of central passwords.
Security is the most important aspect of every operating system. When this package is not installed the user information including passwords is stored in the /etc/passwd file.
The password is stored in an encoded format.
The Shadow Package solves the problem by relocating the passwords to another file (usually /etc/shadow).

I hope you understand it.

Thanks,
Shemeer

The key elements of protocols are
a. Syntax
   It refers to the structure or format of the data, that is the order in which they are presented.
b. Semantics
   It refers to the meaning of each section of bits.
c. Timing
   Timing refers to two characteristics: When data should be sent and how fast they can be sent.
