Can Siemens DECT/VoIP phone S450IP be used for Yahoo Phone Out or Skype Out?

Question

Can Siemens DECT/VoIP phone S450IP be used for Yahoo Phone Out or Skype Out?

Answer 1

No, it will not.

Yahoo Phone Out and SkypeOut are not SIP based services.

However, it does support instant message text chat with Yahoo Messenger, ICQ, AOL, Google Chat using its Jabber client.

As far as VoIP voice calls, it will allow you to register with up to 4 different "SIP-based" VoIP services that support BYOD (Bring Your Own SIP Device).  

Two SIP-based VoIP services that I personally prefer and subscribe to are InPhonex and CallCentric. (links through my profile).

I also use Les.net, Voip.ms, Ideasip, and SIPphone for making many of my SIP-based VoIP calls.

Any of these SIP VoIP services can be configured into the Siemens S450 IP phone.

Answer 2

No....The protocol in most cases are different. This phone is a SIP (session initiated protocol) Yahoo phone and Skype are totally different. I hope that helps.
