When I start to dial, I sometimes forget whether I’m dialing over the PSTN or over the Internet (VoIP).

The X5v has a distinctive, lower-pitched dial tone when it is in VoIP mode, compared to the standard phone dial tone for your country. If you do not notice the X5v’s change in dial tone after you press # to begin a VoIP call, we recommend that you change your VoIP dial tone to make it more easily recognizable. See page 34 for help changing your ring tones.

Sometimes it’s hard to understand people on VoIP calls.

If you are making or receiving VoIP calls during a period when there is very heavy Internet traffic, you may notice an effect on voice quality. For example, you may encounter a delay in hearing the other person talk, or there may be brief intervals where it’s difficult to understand what the other person is saying. Sometimes this is unavoidable. Your service or some other connecting link between you and the person you are calling may become congested. If someone is using the ADSL line to download or upload large files—music or video files, for example—while you are on the phone, it may affect voice quality. You may want to avoid this situation.
