Silverlight SIP phone with frre trial sample programs

[francisco]

Hi! As a developer I need to develop a SIP webphone in visual studio using Silverlight applications. Does your provider promote compatibility with applications related to a sip webphone and does it have free trial sample programs like this one too: www.voip-sip-sdk.com/p_83-silverlight-sip-softphone-javascript-voip.html  which is based on an sdk. (I added this site for showing you the example program of an sdk.) Thank you for considering my question.
