Hi, thanks for the reply. I haven't found an expires paramater of usrloc module, maybe you mean the expires of registrar module: modparam("registrar", "max_expires", 3600)

If it is so, I have tried with the same value for presence and registrar modparam("presence", "max_expires", 3600) and with presence expires greater than the registrar expires modparam("presence", "max_expires", 4000)

I have repeted the test and I have seen that the error messages occur when I deregister and reregister the subscribed client, but I think that the error could be related to the fact that the subscriber (Eyebeam) refuses the first NOTIFY (why?) sended by openser for the first REGISTER from the subscribed.
