[cisco-voip] C3945E is going out of service

[Maciej Bylica]

Hello,



I have Cisco 3945E working as pure CUBE, running
c3900e-universalk9-mz.SPA.152-3.T.bin.

CUBE has been working fine for months, but yestarday i had 2 times 2-3mins
oos, today it was 5 times.

Cisco is lossing any connectivity, sending no response to any SIP messages,
ssh session is terminated, ping shows no connection. After 2 or 3 minutes
cisco is back again, but voice RTP traffic is 1/2 comparing to before the
issue.

This midnight cisco had been rebooted, but the problem still persist.



Running debug ccsip errors show a lot of strange info:

but as i remember these errors were all the time, even months ago.

I am sure that there was no configuration changes that may change the way
cisco is working lately.

OOS are observed even in non peak hours.

all dialpeers have the same sets of codecs in incoming and outgoing leg.

I have transcoding functionality available (via sccp).



Could anyone help me to figure out where the problem is located?

What other info are needed to get into this?

Maybe this is because of
CSCsm92688<https://www.cisco.com/cisco/psn/bssprt/bss?searchType=bstbugidsearch&page=bstBugDetail&BugID=CSCsm92688>
(unfortunately
i cannot fine any detailed info regarding this, not have TAC access) bug?



Today i will try to downgrade the IOS (to 15.1(4)M1) , but i am not sure
because 15.2(3)T was working quite fine for long time.



Thanks in advance

Mac
