Runs a simple parking scenario where a call is sent to a media server then picked
up by the called entity later.

#### 27.top-hiding-reject
Run the same as [25.top-hiding](#25top-hiding) scenario, but send re-INVITEs
which are rejected.

#### 28.top-hiding-overlapping
Run the same as [25.top-hiding](#25top-hiding) scenario, but send re-INVITEs
in such a manner that they overlap.

#### 29.refer-unattended-uas-491-uas
Runs a b2b transfer scenario where there is a race between a re-INVITE
generated by the caller and the one generated by the referee. In this case,
the referee/uac sends its re-INVITE after the 491.

#### 30.refer-unattended-uas-491-uac
Run the same as
[29.refer-unattended-uas-491-uas](#29refer-unattended-uas-491-uas)
scenario, but the referee no longer sends the re-INVITE, thus we retry
the bridging after 2.1-4s.

### UAC Auth

Verifies the behavior of uac_auth module.
