A good starting point would be the Asterisk documentation and forums:

Putting your own company logo on a VOIP phone is a common thing, and you don't need to modify firmware images to do it. It depends on what kind of phone you're using, and whether it supports that or not.

...which doesn't matter at all, since by putting whatever image file you want into the directories given to you on the Asterisk forum will make the logo work.

iam successfully extracted its firmware using binwalk tool its image file stored in '\var\lib\asterisk\static-http\config\images\logo.png'

So if you've already extracted it, why did you open a thread asking how to extract it???

but i don't know how to rebuild this firmware i try lots of tools but device doesn't support my file. i'm newbie in embeded architecture please help me as soon as possible

This is a VOLUNTEER forum...we answer when we can, so telling us to help you 'as soon as possible' is fairly rude. Again, you DO NOT rebuild the firmware...you simply copy the logo files into where your asterisk software goes, into the appropriate locations. Done. AGAIN, this will only work if your VOIP DEVICE (that is, the phone that sits on someones desk), supports that feature.

There are also tools to let you do such things:
