Issue Description
When you call from out side you can hear the IVR but when you press the digit for the choices like 1- for English  , 2- For arabic ,  ...etc  , there is no responce at all .
Alarm Information
only no response , and all the status are normal .
Handling Process

1- I called the VU from internal Extension , and it's working well .

2-configured an extension as a default incomming number and make sure that i can recive calls on this exyension , and i ca hear the DTMF tone.

3-i checked the codec using the following command show mrsparas and i found it ULAW and this is the probem .

4-I changed the codec to be ALAW using this command [config modify mrsparas tdmcodec alaw  ] .

5-after changing the codec evry thing is going well.

Root Cause
the mismatch on the codec type it must be ALAW not Ulaw  .
Solution
-I changed the codec to be ALAW using this command [config modify mrsparas tdmcodec alaw  ] .
