Send uuid_media_reneg only after ACK recieved

Is there a way to have FreeSWITCH hold a uuid_media_reneg until after the ACK has been received for the 200OK

We are triggering this on the aLeg but sometimes the ACK back from the SIP Handset is a little slow so want to hold this until it’s received…

I know we could wait a bit before sending it but it would be more optimsed if it sent it only after the ACK came back…

I dont think any of the exec_after or execute_after count for us because they are not waiting for the ACK back to the 200OK sent from the aLeg unless i am doing something wrong.

Thanks
