Applies To

This information applies to

  • IP 6000, V6 SR1
  • IP 800, V6 SR1
  • IP 302/305, V6 SR1

More Information

  • Which size should the card have?

The card should have at least 64 MB, because it uses FAT32.

  • Is there a formula to calculate the space for one mail box user?

Assuming we have G.711, a voice mail (120 seconds maximum) has 960 kb, because 8 kb/s are used and assuming we have G.729, a voice mail has 120 kb, because 1 kb/s is used. So it's now on you to estimate the amount of voice mails one of your users will have and how many voice mail users you have.

  • Is there a recommended card speed?

The card should have at least a read/write speed of 8 mbit/s.

  • Are there recommended manufacturers/cards?

Yes. We recommend to use SanDisk cards, because we made the best experiences with them. But in general, each card should be supported. For SanDisk cards, please use Ultra II or above (Extreme III/IV).

  • Is it possible to put MOH on the compact flash card?

Yes, this is possible.

Known Problems

  • Till now, the ip6000 has problems with certain cf card manufacturers. Please use the recommended Sandisk cards here.
