CUE AA transfer to B-ACD script no sound

Hello Community, 

I am having an issue with AA and B-ACD.

When a call comes in, it is sent to AA, which is only used to check the time. If the time falls between the opening hours, then transfer to the B-ACD script, running on the CME. 

The caller then gets the menu prompt played, and they click their option. The user is then placed into the queue. They hear the MOH, and all is good.

Then the operator picks up the handset, and the call is connected. The call however is silent. No communication can be heard by either party. 

 

I am able to tell when this is going to occur, as the terminal monitor shows the following: 

VCC, mtp1 index, mtp2 index, stream1, stream2 = 0 0 5 6 VCC, mtp1 index, mtp2 index, stream1, stream2 = 0 0 6 5

Any Ideas?

 

 

Many Thanks!

Joe

Thanks. I shall test it, and

Thanks. I shall test it, and come back to you. BTW, I need dtmf-relay h245-alphanumeric, as otherwise the user cannot select a menu option :)

 

 

I understand why it should be G711u, but As I have Voice Class Codec 1, I had presumed it would look through that for the correct codec? How come this is not the case?

Can you elaborate on

Can you elaborate on "sometimes"? Does this mean there is 2 way audio also?

Can you take packet captures on the router physical interface towards the WAN?

Here's a document on taking the captures:
