We need a SIP Webphone for you website.
It should have hardcoded the server sip address.
Call, Hang Up buttons. (Redial by clicking 2 times to Call)
Small buttons "Audio Settings" and "Logout"
Codecs used: g711 aLaw, GSM, g729 (One of them is fine)
The interface should be skinnable so that it can be changed later.
We understand that the budget is too low but unfortunately we cannot provide more.
We can provide more information in case we agree with the project.
Thank you in advance
