In the last few weeks a large sleeping troll has come out of hibernation and seems set on disrupting the whole voip market.
“BT is engaged in licensing an extensive range of standards related patents that address the key features of SIP Trunking providers and VOIP operators providers.
BT’s Patents address a wide range of fundamental capabilities now in widespread deployment, such as:
- Setting up a call
- Breaking out to other networks
- Managing resources efficiently
- Registering terminal to a network
- Cost effective call completion
- Monitoring and alerting of IP call quality”
Well that pretty much covers all of the workings of a SIP network. A full list of the patents is here .
But its not Just BT, AT&T also have claims over SIP as well see here for a list.
It seems that some of the major patent holders see more money in the licencing of the now ubiquitous SIP protocol than maybe supplying it to customer. Which is a shame as the only ones who will make any money will be the Lawyers in the end.
More to follow on this I’m sure….
