1. Use System Software Version 3.2 or higher.
2. Features that use # are normally not available since this is normally the ATA Send digit. These features include:
   • Line Dial-Up (dialing #901 to access line 1).
   • Conference (dialing #10 to set up a Conference).
   • Meet Me Conference (dialing #10 or #11 to join a Meet Me Conference).
   • Outside line Flash (hookflash + dial #3).
   • Removing Lines and Extensions from Service (#40 + 4 or 6).
   • Group Call Pickup (dialing *# to intercept a call ringing the same group).
3. If an ATA calls an extension that is busy or in Do Not Disturb, they'll hear busy tone and should try again later. Voice prompts and dial options (such as dialing 2 to Camp On) are not available.
4. Line Camp On and Line Callback are not available at an ATA.
5. The INTERCOM + *3 dial codes can not be used to set up Call Forwarding. This applies to both ATAs and analog SLTs. Use Extension Hunting instead.
6. When Paging from an ATA, dial *1 + Zone (1-7 or 0 for All Call). The ATA user does not have to dial the concluding #.
7. Prime Line should normally be set to Intercom for an ATA. If set to Line Key, Line or Line Group, the ATA user won't be able to place Intercom calls to the main system.
8. Ringdown should normally be disabled for an ATA. If you set Ringdown to go to extension 301, for example, any digits the ATA user dials will be discarded after they press # to send the call. It will be routed to extension 301 instead.
9. An ATA user cannot dial *# to pick up a call ringing their own Group Call Pickup group. The # sends the digits which precede it (which in this case is only the *).
10. Directed Call Pickup is not available at an ATA since the ATA does not permit ** in a dial string.
11. Unscreened Transfers are recommended.
12. If an ATA user hookflashes while on a call and hangs up, the call recalls to them immediately.
13. (Prior to 3.20 Only) With P2P on the LAN enabled, doing a Make Call (MC) between two STLs connected to the same ATA will likely result in a one-way speech path. There are two solutions: port forward the PAP2T RTP ports or disable P2P on the LAN.

Unlike the DSX IP Keyset, the Cisco SAP8000 and PAP2T ATAs require some basic setup programming to make them work correctly on the DSX. If you don't understand the following options, refer to the Cisco documentation for additional instruction.

To have access to these options, you must log onto the ATA as admin and run in the advanced mode.
