I met with Mike Wilson, VP of Sales & Marketing for UM Labs at ITEXPO today to learn more about their secure VoIP offering. At ITEXPO they announced their 1.5 release, which steps up interoperability amongst various IP-PBXS and now it works with Skype (Skype Connect).
Mike explained that a lot of independent dealers across the world who also use Skype, can now connect their PBXs to these Skype users and save a lot of money on conference calls. Their solution acts as the "glue" allowing Avaya to connect to Cisco, or Shoretel to Avaya, etc. They have a built-in scripting engine and can adjust paths between switch and trunking provider or two switches to ensure interoperability.

As part of this release they are stepping up encryption, which he claimed already had incredibly low latency. They now support 256-bit AES encryption from 128 bits. Further, they made it work on cell phones, such as Nokia. That's impressive considering you need a decent amount of HP to do 256-bit encryption, which the Symbian platform often doesn't have. Symbian users using a SIP softphone app can now make 256-bit encrypted calls, which Mike said is huge in the financial sector. He said they are porting over to iPhone as well.
