| Can I use the Callcentric service with a dialup modem? |
 |
Yes, you can use the Callcentric service with a dialup modem of 28.8 kbps or faster. However, in general you will find the Callcentric service to be less reliable and you may experience quality problems with calls on a dialup connection. We strongly recommend that you use the Callcentric service on broadband Internet connection such as ISDN BRI, DSL, Cable, T1, E1, Wi-Fi, Wi-Max, etc.
In order to use the Callcentric service with a modem connected to your computer, you will need user agent software that supports the G.729 codec. For more information on software user agents such as X-Lite and X-Pro, please visit the support area to see compatible software. |
