Programming an IVR in KX series? Programming an IVR in KX series? skulmat (IS/IT--Management) (OP) 9 Mar 18 01:11 Where would I program the IVR for a KX-TVA or KX-TDA ? And where do I set it up? Thank you RE: Programming an IVR in KX series? WhiteGooner (Programmer) 9 Mar 18 10:33 You will need an OPB3 with DISA card or get a TVM. I dont think TDA has built in DISA RE: Programming an IVR in KX series? obtsystems (Programmer) 9 Mar 18 22:20 Whitegooner is correct no disa by default. Opb3 ans esvm card for 100/200 or esvm card for 15/30 RE: Programming an IVR in KX series?

They connect to the phone system i.e. kxtda, kxtde or ncp via a digital proprietary phone port which gives you two voice channels between the two units and all the handshaking. The ivr is programmed using custom service menus of the kx-tva/kx-tvm. Or as the guys have said above get the esvm card to go on the tda, tde or ncp.
