There are security measures that can be taken to make SIP trunking enterprise-worthy, but there is also a lot of hype about such solutions, creating a good deal of confusion. To cut through this confusion, a free Webinar, Secure SIP Trunking: What You Need to Know, will be held April 10, 2008 at 2:00 p.m. ET (11:00 a.m. PT). This Webinar will be presented by Steven Johnson, president at Ingate Systems (News - Alert); Dan York, Director at Voxeo and chair for VOIPSA; and Erik Linask, TMCnet Group Managing Editor.
Johnson, York and Linask will explain which SIP trunking security measures work, and which don’t. The discussion will include a look at common SIP trunking security misconceptions, along with the requirements for overcoming challenges. The presenters will also explain how SIP trunking can be more secure than traditional telephony.
Included in the presentation will be a rundown on the basics of enterprise security and VoIP, new security technologies now available, and how to future-proof networks.
