We will install new firewall cards in front of the telephony infrastructure.
These cards are intended to protect infrastructure and allow future developments.
The impact will be about ten minutes.
The intervention is scheduled for Thursday 26/07 at 1:00
Date: 2012-08-08 03:46:53 UTC The clusters' setting have been standardized.
The service is running properly.
Date: 2012-08-08 03:45:06 UTC All tests have been successful thereafter switching.
We will continue monitoring the equipments.
Date: 2012-08-08 00:00:24 UTC The firewall card is working properly.
SIP phones are operational. MGCP phones need a little longer to return.
Date: 2012-08-07 23:52:05 UTC Operation started, we began switching the IPs.
Date: 2012-08-07 22:42:56 UTC We are verifying the setting.
Date: 2012-08-07 22:19:07 UTC The operation is planned for Wednesday, August 8th from 0:30.
We will install a new configuration in the firewall cards.
We are trying to have the easiest and the most stable configuration as possible.
Date: 2012-07-26 05:41:19 UTC The service is operational again.
We are checking that the last phones re-record themselves correctly.
Date: 2012-07-26 05:40:28 UTC The rewind causes some difficulties.
We are endeavouring to restablish the service as quick as possible.
Date: 2012-07-26 05:39:09 UTC The firewall card held on. however, we found out a cirpack bug which prevents from accepting more than 32 SIP connections at the lever of the proxy on 1 singel couple ip/port.
Analyses are in progress at the level of the manufacturer to understand and identify the bug.
Rewind. We stop for tonight.
Date: 2012-07-26 01:16:06 UTC Network team has found an error in the setting which could explain this saturation.
We are retrying to produce a firewall card.
Date: 2012-07-26 01:14:58 UTC Last telephones MGCP are properly reconnecting.
Date: 2012-07-26 00:19:00 UTC The backtracking is OK. The configuration is identical to that before the operation.
We are checking the MGCP phones.
Date: 2012-07-26 00:17:14 UTC # sh cpu usage
CPU utilization for 5 seconds = 97.8%; 1 minute: 97.8%; 5 minutes: 97.7%
Date: 2012-07-26 00:16:59 UTC The call routing is very long. the firewall card is unable to collect the traffic.
We will backtrack.
Date: 2012-07-26 00:14:12 UTC The configuration was successful. MGCP and SIP phones are being registred.
Date: 2012-07-25 23:53:47 UTC We started the operation.
We began by moving the IPs.
Date: 2012-07-25 23:52:51 UTC We are checking the firewall cards' configuration.
