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.

General communicate service [SEWAN] Unexpected disturbances - 10.06.2021

   

Beginning: 10.06.2021 – 2.36 PM

Ending: 10.06.2021 – 5.30 PM

Impact: Degradation of overall voice quality

 

Dear customer, dear partner,

 

since 2.36PM today, we experienced iterative problems in reachability and packetloss. This resulted for some customers which were routed to us over several IP Transit providers in calls being cut, registrations being lost and bad quality in the calls. After checking with two of these carriers, the problems were confirmed to find their origin in Packetloss in one of the major backbones in Brussels, due to a very high volume of traffic they had to cope with.

At 5.30PM, we were informed the problems were totally resolved at their side.

Our apologies for any inconvenience this may have caused.

 

Best regards;
