I saw this on a customer’s system where calls were being disconnected when the * button was pressed during the call.
This was being caused by 2 settings. The first being the default Asterisk feature code for disconnecting a call. You can see these at the Asterisk CLI like this –
So you can see there is a default feature code for disconnecting the call by pressing *
This setting will only be honoured if you have a ‘H’ or ‘h’ in the Asterisk dial command in A2Billing. To check this go to settings and the agi-conf you are using and look for the dialcommand_param and if there’s a ‘H’ or ‘h’ in there take it out –
It could be useful to have it in there if this agi-conf is used by calling card customers and you want to enable them to make follow on calls, but not for SIP customers.
