I have not used this product myself, but something like this could work, http://www.matrox.com/video/en/products/compresshd/ The company does have an SDK version but be ready to pay for it, its not cheap in terms of one end point. I have also looked a DSP board from Octasic but it is more designed for larger scale media gateways but could be used for SIP end point. I am currently research Intel's IPP but, I've read there are some features in Intel's IPP encoder that are required for RTP streaming that does not exists. TI's OMAP 5 looks promising.
