    newParentStack - Parent stack for this transaction.
    newEncapsulatedChannel - Underlying channel for this transaction.
- Method Detail
  - getBranchId
```
public String getBranchId()
```
    Description copied from interface: Transaction
    
    Returns a unique branch identifer that identifies this transaction. The branch identifier is used in the ViaHeader. The uniqueness property of the branch ID parameter to facilitate its use as a transaction ID, was not part of RFC 2543. The branch ID inserted by an element compliant with the RFC3261 specification MUST always begin with the characters "z9hG4bK". These 7 characters are used as a magic cookie, so that servers receiving the request can determine that the branch ID was constructed to be globally unique. The precise format of the branch token is implementation-defined. This method should always return the same branch identifier for the same transaction.

```
public void setRetransmitTimer(int retransmitTimer)
```
    Description copied from interface: SIPTransaction
    
    Sets the value of the retransmit timer to the newly supplied timer value. The retransmit timer is expressed in milliseconds and its default value is 500ms. This method allows the application to change the transaction retransmit behavior for different networks. Take the gateway proxy as an example. The internal intranet is likely to be reatively uncongested and the endpoints will be relatively close. The external network is the general Internet. This functionality allows different retransmit times for either side.
