Folks, I am trying to make calls to test a IVR Machine with SIPP. First, I am using the Sipp v1.0 final version. But this version does not have support to send digits to IVR Machine. So system is unable to answer calls. I tested using other versions too.

Here is my scenario:

<!DOCTYPE scenario SYSTEM "sipp.dtd">

<scenario name="Basic Sipstone UAC">

But, the answer is that (when I am using de version 1.0):

2017-11-16 19:31:46: Unknown element 'nop' in xml scenario file.

Please, help me.

SIPP can do complex SIP scripts but it is very limited for Voice interactions...

If you plan to test the IVR with Voice/DTMF interactions, try with Asterisk. You can use a Dialer Script (We can provide one) to apply to your IVR a charge, with a Dialpan you can create complex scripting (with random).

  • I'm calling from SIPP and Softphone to a ivr machine. When I call through the softphone, I get the 200 and I send the ACK. When I call through the sipp using the scenario below, I get a lot of 200 but ACK is not sent by sipp. Can someone help me with this case? Is there a mistake in the scenario I created? please help me. – Geovani Carvalho Nov 21 '17 at 15:43
