Do busied stations lose their H.323 registration?

I busied a 9620 station today but it's still registered. At what point does it become unregistered, if ever? If busying a station doesn't unregister it, how would you unregister phones remotely w/out actually touching them?

Na. Busied = CM doesn't let them complete registering. I'm not sure if it sends a 'register deny', but busying a phone out doesn't make the phone flush it's NVRAM.

It's been a bit of a discussion on these boards about what exactly a phone retains and flushes and when.

What I can tell you is that a phone will flush credentials if they're wrong - so in the SIP or H323 world, if you were to reboot a phone and change its password while that's happening, then when it comes up again and says "i'm extn 1234 pw 1234" then getting the 'invalid pw' message makes it drop to 'pls enter extn and pw'

SIP re-registers every hour with a pw prompt in the SIP signaling.
H323 registers once and keepalives don't contain the pw.

You can change a SIP phone's pw and it should drop in an hour
You can change a H323 phone's pw and it should still work till the phone logs out/reboots

So, change the PW in CM, reboot the phone with reset ip-stations

Latest SIP firmwares support "GET $MACADDR.txt" and you can have unique .txt files per MAC address with extn/pw in them.

SLA Mon - included in the SAL gateway if you chose to install the package, lets you specify in 46xxsettings that the phone can listen on a port and be 'discovered' by SLA Mon and let you take remote control of the phone from a webpage as long as the phone is online whether it's registered to a PBX or not. So, you can camp on a real phone with 'Connecting...' or 'enter extn/pw' on the screen and hit the craft menu or key in the extn/pw yourself from the comfort of your own basement.

Thanks. I busied a station, waited a good 18 hours, set never unregistered. you can stat the phone, it says "disconnected" but still registered. I just wish there were a way to unregister a phone via the PBX other than the reset ip-stations command. seems the only way around this is to walk over to each station and log it out. now what i would like to do but i know it'll work.

You can unregister a set from CM Command: prompt

reset ip-stations ip-phones ipaddr ww.xxx.yy.zz ww.xxx.yy.zz
