Resolved - This is resolved and was isolated to a small number of customers over the period from 1254 and 1258 only and calls that arrived via our Slough site only. It is likely that some calls succeeded (despite notices being sent indicating their rejection) as they will have been re-tried over another route. Where the call actually failed callers will have heard a number busy tone.

We're still investigating the underlying cause and apologise sincerely for any inconvenience caused.
Aug 8, 13:09 UTC
Investigating - We are aware a small number of customers have briefly had calls rejected with "Inbound Channel Limit Exceeded" messages in error between 1254 and 1258, we're investigating this as a priority and will update this with more information as soon as possible.

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.

Scheduled - Kamailio today released a security announcement CVE-2018-14767 (more information below) which affects some versions of Kamailio that we run.

Kamailio is a well-established open source SIP proxy that we use on our network edge to filter and load-balance traffic as well as handle some unusual compatibility edge cases.

The nature of the vulnerability enables a Denial of Service (DoS) attack and, therefore, we've taken the unusual decision to deploy upgraded edge proxies as emergency maintenance during the day. This will result in a brief (under 30s) interruption and has already been tested in our lab, additionally, our international sites have already been upgraded.

We regularly maintain and update our platform, and this update has been tested internally and was scheduled to happen in the coming weeks anyway, however, the release of this vulnerability together with exploit code necessitates it being brought forward.

Customers configured in accordance with our interop information, using DNS and SRV where possible, should not see any interruption. Those monitoring our IP addresses directly will see a brief period where a site may not respond to OPTIONS requests.

We are also aware that many of our customers use Kamailio and, if you have not already done so, urge you to update to the latest supported versions. This vulnerability affects all versions prior to 5.0.7 and 5.1.4 and possibly OpenSER.
