Beginning: 30.06.2021 – 2.37 PM

Ending: 30.06.2021 – 2.41 PM

Impact: V5 traffic disturbances

 

Dear customer, dear partner,

 

We experienced a breif overload on incoming sip messages, which made the processing of sip messages slower, with a maximum measured delays upto 7 seconds in signalling. A backup service took over the load, which restored normal functioning of the service.

In order to permanently fix this issue, we are planning both with our vendors several upgrades of our software, among others : Kamailio 5.5.0, Freeswitch 1.10.6 and rtpengine 10.0

Please remain certain that we take this matter seriously.

sbcng.sewan.be (V5) [SEWAN] Unexpected disturbances - 18.06.2021

   

Beginning: 18.06.2021 – 10.37 AM

Ending: 18.06.2021 – 10.48 AM

Impact: V5 packloss and lose of registration

 

Dear customer, dear partner,

 

We experienced today 11 minutes of problems with an RTP media gateway. There were scenario’s in which a loop was not detected, which resulted in quickly growing rtp stream. This could quickly be resolved case-by-case, by finding the culprit stream and kill it. Yet, this was not a long term solution, as it gave unexpected issues on the platform, like slow responses on SIP messages.

While debugging this, the quickest way to come back to a full resolution, was a restart of the registrar, which broke sip registration for a brief period of time. (until next registration)

With the software team of this product, we were able to receive an updated version ending of last week, which was rolled out on one gateway so far. The first results are very promising, the loops do not occur.

We are planning to upgrade all our media gateways to this version.

Our apologies for the inconvenience.
