Call-in-one phone
Today SIPPhone announced that they have started to market an adapter that has both PSTN and IP interfaces can route a call to either of the network. This is in contrast to the joint announcement from Skype and Siemens regarding a similar device. It is a good development in that the industry is paying attention to the devices rather than service providers.
Unfortunately there are no further details on the capabilities of this device and I have so many questions:
- Can the device register for multiple accounts? To multiple proxies?
- Does it generate Caller ID on the FXS port?
- If I am on a SIP call and a call comes on the PSTN interface, what happens? A call waiting tone on the FXS port? How about Caller ID?
Let me know if you know the answer.
Update: After exchanging a few emails (they are prompt and complete in answering your questions) the answers to my questions are:
- The device can register to only one proxy
- It does generate Caller ID
- Call waiting works only on the same interface. So if you are on a PSTN call, the call on the IP interface will go unansered and so forwarded to voice mail.
