Skype to SIP Possible, In Use
Image via Wikipedia
One of the more frequent complaints I hear about Skype is that it doesn’t interface with SIP. Of course, people in the know know that Skype must use SIP to deal with SkypeOut and SkypeIn, but are simply refusing to expose that functionality to others.
What is interesting, through, is that Skype has exposed Skype to SIP in a limited fashion. At least two application providers, namely Voxeo and Vapps, both use this functionality. It is exposed by dialing a rather lengthy +99 number from Skype, permitting Skype to dial into Voxeo’s Evolution Hosted Platform and Vapps High Speed Conferencing service. Possibly others.
The benefit of this functionality is it allows Skype to dial into these services and be able to utilize G.722.2 (a.k.a. AMB-WB). This means your audio into these services will be much higher fidelity. Trust me, after hearing the difference, I’m a believer.

Read my blog entry “A free bridge from Skype to phone”! I explain how calls to my Skype account ring my phone or cell phone. For free.

Dameon,
Thanks for the mention and yes, we (Voxeo) do support inbound calling via Skype on our Evolution hosted platform. We can’t do *outbound* calling into the Skype cloud as Skype does not (yet, anyway) allow that, but inbound works great. I wrote up a piece about this (in response, amusingly, to Markus’ post he just mentioned) that goes into more detail:

As a network/telephony geek, it was definitely one of the fun things to learn about about when I joined Voxeo six months ago.
Thanks,
Dan

call forwarding from a skype account to the +99 numbers works; so callers do not need to enter the long +99 numbers if you have the forwarding setup.

@spg that’s a good thing.
