Hello, all. There is a question about operation as a register server. I read RFC3261 and it was interpreted as the ability of register server to determine expire of register preferentially. Although sip.conf has a setup about expire of register?defaultexpirey,maxexpirey?, this setup is a setup which influences when operating as register client, and cannot make register client force into expire as register server. Is my setup mistaken? Or does my interpretation apologize? Is it the specification of Asterisk again? I need your help well. Ichiro Nakata test0625a@mbs.sphere.ne.jp
