Blink Help Center

To use Blink you need a SIP account from a SIP service provider. Similar to using an email program, you must configure Blink with the account you have obtained from your service provider. If things do not work the way you expect, there can be several reasons.

The cause may be located by Blink software itself, the network connectivity or the SIP Service Provider. While Blink may not be bug free, based on experience so far most of the problems are related to the network connectivity (packet loss, presence of a broken SIP ALG router) or/and the SIP Service Provider (most providers only support Voice calls). It is not the end-user who should understand the mechanics about how things work, so the main responsibility of making sure that things work correct falls into the hands of the SIP service provider who must properly setup its SIP infrastructure.

To eliminate some possible causes, try to use the built-in accounts provided by Blink, all features are known to be working using these accounts.

Known problems introduced by OSX 10.12

Since Apple introduced OSX 10.12 (Sierra), it forced all developers to use Xcode 8. Building with Xcode 8 introduced various problems for many applications, Blink included.

  • Video calls cause application to crash (on OSX 10.12 only). We identified the cause in a Apple library and still wait for a fix. Alternativelly, we can devise another video rendering strategy, it no fix becomes available from Apple.
  • Latest Blink crashes on any Mac using Intel Core 2 Duo processors. Don't upgrade to latest App Store version if you use such architecture. We work on rebuilding all Blink dependendencies in a way that makes it compatible with all past architectures.
  • Random crashes in refreshing Contacts list on 10.11 and 10.12. The crash report shows these lines "[NSTableView _shouldUseSecondaryHighlightColor]". The cause is unknown yet.
