Simulate video by streaming a short .mp4 video sample using VLC and a virtual switch in GNS3.
Sending PC sending stream using destination RTP/MPEG Transport Stream to address 224.0.0.1 port 5004.
Receiving PC play URL rtp://@224.0.0.1:5004.
Tip: On sending PC select Properties>Show Settings ALL and under Input / Codecs, Video codecs, FFmpeg enable Allow speed tricks and set Skip the loop filter for H.264 decoding to ALL. Save. This stops the sluggish behaviour on the playback from the sending PC. Even sluggish when plays back locally.
Transcoding options:
Select Activate Transcoding. Profile Video – H.264 + MP3 (MP4).
Miscellaneous Options:
Select Stream all elementary streams.

PBX:
Manage with FreePBX GUI by connecting browser to IP address of the AsteriskNow host machine.
Voicemail:
*97 = check voicemail
*98 = check any mailbox
Soft phone:
Tip: AsteriskNow acts as a bridge between two SIP phones. Use GNS3 wireshark to capture UDP traffic on either leg. Decode UTP traffic as RTP and Play Streams back using RTP Stream Analysis. It is possible to play back G711 codec.

To stabilize the two mouse pointers inside the Windows VM console add -usbdevice tablet in the options box in the Advanced settings>Additional settings screen.
Tip: Enable remote access so that can setup RDC to Windows VM.
Tip: EULA is for 90 days. User = IEUser and Password = Passw0rd!
Tip: Temporarily disable FW to prove ping test works.
Several references to an appliance created by GNS3 team for accessing the internet but could not find the appliance internet.gns3a template under marketplace on GNS3 website (also tried to bridge my loopback adapter to my Wifi using a Cloud which failed), but did manage to get internet access using the NAT cloud option.
Tested with VPCS (ip dhcp) / Firefox (enable dhcp) to get an IP address, DNS etc… and could ping public IP addresses and also resolve names to IP addresses.
Tip: As NAT cloud only has one interface add a generic Ethernet Switch to it in the topology, this way it is possible to use multiple end devices.
Can also add a firewall such as pfSense between the generic Ethernet Switch and the NAT cloud.
