Hi, This is very true and could be really frustrating if you need presense. OpenSBC currently do not process SUBSCRIBE messages and would respond with a bad extension by default. I am planning to work on this for version 1.1.6. The real problem is not really the incapability of OSBC to relay SUBSCRIBEs to upper-reg but the requirement to rewrite SUBSCRIBE messages the same way as its REGISTER counterpart. It's a bit tricky.
