hello,
good day! anyone who’ve encountered a sip client not registering but the * server says it’s registered? what i mean here is 1 of my grandstream ATA’s (486) are flashing red continuously which means it’s not syncing to my * server but when i check it, it’s registered and has an ip which means the server recognizes the ATA. how can i unregister that one sip client without shutting down asterisk or the whole linux box? this one’s a li’l weird for me, but if anyone already had encountered this little problem, can you please give me some advice on how to act on this. thanks in advance, 
ryan
