Call extensions

I need to call phone number with extension. I saw in knowledge base that I can add ,,,, to add pause. For example to get to extension 366, I can do 1-800-456-5678,,,,,366. I tried yesterday with skype, but does not work. Skype says 1-800-456-5678366 is not a valid number. Somehow voicnt is not adding pause for ,,,,. Can you suggest a way to get this working?

The comma will only work for analog phone line with modems. For VOIP service, such as Skype or SIP based, the comma won’t work. The reason is that the way a call is connected using analog phone line is completely different from using VOIP. However, you should still be able to dial extensions. The answer is described in the previous article about call hotel room with extensions.
