776d323a16 fix: Change UE Context Request IE handling (#771)
Previously, AMF would sends PDUSessionResourceSetupRequest
when the following conditions were met:
- gNB didn't send UE Context Request IE of InitialUEMessage
- AMF should send SMF generated TRANSFER message(PDU_RES_SETUP_REQ)
to the gNB

However, in issues #771, the gNB did not accept
PDUSessionResourceSetupRequest. Perhaps the gNB engineer thought
that if gNB needs to send data traffic to the UE, AMF should send
an InitialContextSetupRequest regardless of UE Context Request IE.
This is because gNB requires the kgNB security context
for data connection.

So, in this case, Open5GS-AMF decided to send
an InitialContexSetupRequest regardless of
whether it received UE Context Request IE of InitialUEMessage.

1c13d7f5ec Legacy support for pre-release LTE 11 devices while performing VoLTE call (#757)
* AAR Media-Sub-Component modification for more UEs support

* Introduce parameter for legacy support for pre-release LTE 11 devices to do calling

IE (IPV4-local-addr field ) is not supported on
the LTE pre release-11 UEs. In order for the call
to work the local address in packet filter must
be replaced by any.

Parameter: no_ipv4v6_local_addr_in_packet_filter

This guide is based on **FreeBSD-11.4-STABLE**.
{: .blue}
## Install **FreeBSD-11.4-STABLE** from Vagrant box (optional)
---
Vagrant provides a simple way to create and deploy Virtual Machines from
pre-built images using VirtualBox, libvirt, or VMWare as a hypervisor engine.
This allows the user to quickly create a virtual machine without the hassle
of installing the operating system by hand.
### Install Vagrant
---
The instructions to install Vagrant are provided at
[vagrantup.com](https://www.vagrantup.com/).
### Create a FreeBSD-11.4-STABLE Virtual Machine using Vagrant
---
Use the supplied `Vagrantfile` in the `vagrant` directory to create the
virtual machine.
Note that this Vagrantfile is identical to the base FreeBSD 11 box, with
the exception that the amount of virtual memory has been increased to 1GB:
```bash
cd vagrant/freebsd
vagrant up --provider virtualbox
```
### Log into the newly created FreeBSD VM
---
Use SSH to log into the FreeBSD 11 VM:
```bash
vagrant ssh
```
Note that the Open5GS source is *not* copied into the VM. The instructions
below provide the step by step instructions for setting up Open5GS for
either a bare metal or virtual FreeBSD 11 system.
The rest of the commands below are performed inside the FreeBSD VM as the
user 'vagrant', or on your bare metal FreeBSD 11 system as any normal user.
### Getting MongoDB
---
Install MongoDB with package manager.
```bash
$ sudo pkg install mongodb44
```
Run MongoDB server.
```bash
$ mkdir -p ./data/db
$ mongod --dbpath ./data/db
```
### Setting up network (No persistent after rebooting)
---
Configure the loopback interface.

```bash

```bash
$ export LIBRARY_PATH=/usr/local/lib
$ export C_INCLUDE_PATH=/usr/local/include
