Robocalls keep coming

A couple of years ago we started seeing an increasing number of incoming “ghost” calls on our codecs.This only affected users who opened the SIP functionality on their devices to be compatible with SIP-based calling apps and WebRTC bridging.

NAB 2018 is over and Comrex introduced four new products! One of them is a new codec app. We’ve been pointing folks to Linphone for years, and it’s great and free, but we often hear it’s too complex for non-techies to set up and use. Enter FieldTap!

Its constant need […]

Tom’s Tech Blog: When the backup becomes the primary

It was nice to read this Radio World blog about Westwood One’s operations during the Rio games. We’re used to seeing big-time broadcasts like this done via ISDN, with IP codecs being relegated to the backup role. But it seems the script has flipped, and IP is now considered reliable enough to be the primary […]

Nifty BRIC-Link Accessory from the UK
