Hi, We are using asterisk version 1.0.5. We have registered two UA's with asterisk. (Registration was successful) UA1 <-------> * <--------> UA2 Now, UA1 subscribes for UA2 to asterisk. asterisk sends NOTIFY to UA1 with UA2's state as open. But if UA2 gets un-registered then, asterisk is not sending NOTIFY to UA1. But when there is state change from UA2, asterisk is supposed to send NOTIFY to UA1 (keeping state as closed). Why is this happening? With regards Somesh S. Shanbhag Firdosh Nasim __________________________________ Do you Yahoo!? Yahoo!
