Hi, I'm new here and got introduced to the SIP standard recently. I have a question, here goes....
Suppose I want to create a gateway/IP phone (not softphone) on my own. Provided I can make the necessary hardwares and the SIP stack, how much cooperation from a service provider do I need? Is there anything called a generic IP phone, which can work with all service providers, or is the hardware dependant upon the service provider? Will a phone made by me work with the CISCO service, for example? I understand the SIP part is probably similar across different service providers, but do they employ some propietary handshaking mechanism at the beginning (authorization, perhaps)? If they do, these mechanisms are classified, right? So the only way to make a IP phone is to tie up with a service provider and make the phone compatible with them only? As an independant SIP developer I can only hope to make softphones then (which will only work with users using MY softphone)? No workaround? I hope I could explain the question properly. English is not my mother toungue, so there's a possibility that I have messed up considerably. Please let me know if you want me to clarify a bit more (I'll try my best). Thanx a lot in advance for yor support. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
