tsearle created an issue (kamailio/kamailio#4249)

### Description

I'm trying to make a SIP Rec callflow using t_uac_send to Generate the INVITE and BYE. This automatically generates the ACK in response to the 200 OK. I want to be able to use tm:local-request to do 2 things.

* Add a Contact header to the ACK * Save Route/Callid/CSeq etc so I can generate an in-dialog bye afterwards.

### Expected behavior

tm:local-request gets called so I can save the relevant headers & modify the outgoing ack

#### Actual observed behavior

tm:local-request does not get called

### Possible Solutions

the associated PR adds this functionality

### Additional Information
