IP Office's integral firewall, service quotas and timebands all apply to remote access calls. Remote access security can be supplemented by CHAP (encrypted passwords) to verify the end users, or PAP which does not support encryption. Timebands can control the hours within which the remote access service is available.

A trusted location can be set for dial in. These are locations that the system will allow either data access, for example, a user dialing in from home, or access to voicemail without a voicemail code for a user collecting their voicemail messages from a mobile. The trusted location is also the location the voicemail server will call to inform the user of a new message.

Conversely a specified location can be set which restricts remote access from only that location, this specified location can also be a designated dial back number thereby minimizing the threat of unauthorized remote access.

IP Office can also incorporate remote access dial back services so that if a user always remotely accesses the office from a single location, for example, their home, then after login verification, the system disconnects their call and dials them back. In addition to the added level of security dial back provides, it can also be an excellent method of consolidating remote access charges onto the central office phone bill.

In addition to remote access from phone adaptors, all ATM4 trunk cards (including the IP500 V2 Combination Card ATM) support switching of the first analog trunk to an integral V.32 modem for remote access.
