What machine to use

We plan an asterisk installation with the following:

  1. An ISDN PRI (30 lines) from the telco (Digium card)
  2. Around 50 SIP extensions (GrandStream BT 102)
  3. A cisco ATA for fax
  4. Concurrent calls expected - 30
  5. May use voicemail, call recording
  6. May scale it to dual PRI and 100 extns. Any change very unlikely for 2 years.
  7. Only want to put one box in place

Can anyone suggest a hardware configuration? Thanx in advance.

can’t say I have any direct experience with the BT102 - but from reading feedback from plenty of users, you may want to consider a more business appropirate phone?

beyond that, you may want to take a look at:
