Does anyone know of a way to directly connect (e.g. via SIP), a CUCM to any public VoIP networks (e.g. Skype, Google Talk etc). Via CUBE would also be ok.
The requirement we have is for a 3rd party PC on the internet to be able to dial into our phone system over the internet, with encrypted signalling and media. Ideally this would be via a publically available client and network so that we do not have to maintain the client configuration, do provisioning etc.
Skype have a SIP service into their network that is in Beta, but it does not support encryption. I'm aware there is also a few Skype gateway products on the market too. Does anyone have experience of using these?
Another alternative would be a web hosted CUCM client, is anyone aware of a 3rd party product offering this functionality?
