Hi.
I have CUCME 10.5 and about 100 sip-phones CP-7821. (All phones and server in LAN)
Sometimes some phone (or may be number) "hangs" - it is always busy. If I call to problem number - it is busy. If I call FROM problem number - I get busy too.
It is happens with random numbers. (sometimes two-three times in a day, sometime once in three days). I don't see any pattern or regularity. Problem phone appears as registered on CUCME. I see periodic "REGISTER" message from phone and "SIP/2.0 200 OK" response from server.
I have to :
conf t
voice register pool <problem number>
restart
for problem phones from ssh on CUCME.
Right now I have "hang" number 7299.
I try to debug with
debug voip ccapi all
debug ccsip all
I've attach log from CUCME (this is test call from 7076 number to "problem" number 7299)
In this log I see
812: NOTIFY sip:7@192.168.160.241:5060 SIP/2.0 (whit last digit "9" in 7299 number)
....
926: SIP/2.0 200 OK (server's response to notify with "9")
...
994: SUBSCRIBE sip:11674-24A@192.168.160.104:49642;transport=tcp SIP/2.0 (from CUCME to phone 7076)
...
1082: SIP/2.0 486 Busy here
But I can't see the reason why 7299 is always busy.
Help me please.

Hi,
Which firmware are you running for 7821 and can you attach sh tech from CME.

Hello,
Do share the show run from CUCME as well as try to disable the authentication register from voice register global and do no create profile and create profile.
!
voice register global
no authenticate register
no create profile
create profile
!
Please add source bind command to voice service voip. Also, try to remove digest authentication (username/password and authenticate register) if any configured.
Collect these debugs and share them too.
debug ccsip messages
debug voice ccapi inout
Sincerely,
Shubhamoy

I've attach file with result of "show running-config" command (it's censored - I delete a large part of "voice register dn" and "voice register pool")
About phone firmware, this line in config:
load 7821 sip78xx.10-2-1-12SR1-4
About modification in voice register global. As far as I understand, after modication I must restart the phones. Is it right? (Right now glitch is on my own phone and I keep my phone turned on for debugging and logging. If I restart my phone glitch disappears and reappears on a random phone.)
I don't find "source bind" command:
Volgog3925#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Volgog3925(config)#voice service voip
Volgog3925(conf-voi-serv)#source bind
^
% Invalid input detected at '^' marker.
Can you give more detail (or link) about "source bind"?
I will collect debug (debug ccsip messages and debug voice ccapi inout) tomorrow.

I've look at log on problem phone (in phone web interface -> "Console Logs"). There are REFER requests from phone to CUCME and "SIP/2.0 400 Bad Request" responds from CUCME.
It is appears that messages don't related with any calls. Problem phone and CUCME periodically exchange REFER and "Bad Request".
In attach - log from problem phone.

Hi
CUCME 10.5 lists 7821 supported with 10.1(1)SR1 , so you may want to double check this with cisco.
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/requirements/guide/cme105spc.html
Also bind command should be applied inside the sip section.
Volgog3925(config)#voice service voip
Volgog3925(conf-voi-serv)#sip
Volgog3925(conf-voi-serv)bind media source-interface interface[]
Volgog3925(conf-voi-serv)bind control source-interface interface[]

Hi
Here is excerpt from "sh flash:" on my CUCME
.....
640 35914072 Jan 14 2015 01:58:36 +03:00 rootfs78xx.10-2-1-12SR1-4.sbn
641 364076 Jan 14 2015 01:59:18 +03:00 sboot78xx.10-2-1-12SR1-4.sbn
642 994 Jan 14 2015 01:59:34 +03:00 sip78xx.10-2-1-12SR1-4.loads
643 3090804 Jan 14 2015 01:59:54 +03:00 kern78xx.10-2-1-12SR1-4.sbn
....
And all phones show in "Phone Information":
Active Load: sip78xx.10-2-1-12SR1-4
If try retreat to 10.1(1)SR1, how can I reflash a single phone for testing?
