All telephone numbers of the IFI’s Voice-over-IP infrastructure are so called ENUM-enabled for incoming calls. If a caller trying to reach you using your phone number is calling over a ENUM capable Voice-over-IP system, it will automatically connect the call over the Internet instead of the traditional phone network.

You may publish your SIP URI on a webpage. Use the sip:sipalias@ifi.uzh.ch format and keep in mind that this address correpsonds to your e-mail address and may therefore be used by spammers.
