Hello

I am trying to deploy a BlueJeans service in the network and am keen to know more about how it works.

Can anyone please advice the Bandwidth requirements to ensure the service works optimally for various different platforms.

Also if we want to ensure prioritization for the BlueJeans service is it best done using ports that the service use or using IP addresses. In either case what the standard ports that are used for the service and the IP address.

Any documents or advice pointing to the above will be much appreciated.

Many Thanks in advance.

Hi Kaushik -

Thanks for reaching out. Did you find our Knowledgebase articles on bandwidth/call quality best practices as well as firewall ports?

Both of these are key's to being successful with Blue Jeans to ensure the highest quality service. 

Here are the details in case you needed to refer back to them: 

Firewall & Port Ranges
Blue Jeans Network uses the following TCP and UDP ports with the service. Make sure to open firewall ports against BJN's entire ip range

  • 199.48.152.0/22
  • 31.171.208.0/21
  • 103.20.59.0/24
  • 103.255.54.0/24
  • 8.10.12.0/24
Note: Blue Jeans has several POPs distributed globally. The call will be automatically redirected to the closest POP to the end point or media egress point.  Audio/video traffic will likely be routed to any of above ip range based on geo location.  Hence it's important that firewall ports are opened against entire ip range. 

H.323 based systems:

Outbound TCP Port   1720 - H.225 Signaling for H.323
Outbound TCP Ports  5000-5999 - H.245 Call Control for H.323
Outbound UDP Ports  5000-5999 - RTP Media

SIP based systems:


Outbound TCP Port    5060 - SIP Signaling
Outbound TCP Port    5061 - SIPS (TLS) Signaling
Outbound UDP Ports  5000-5999 - RTP Media

Browser, Mobile app and Google video chat:   Outbound TCP Port   443, 5061 - Call Setup Signaling
   Outbound UDP Ports 5000-5999 - RTP Media   [Note: If your web traffic routes via an HTTP Proxy, please create an exception to allow web traffic to route to *.bjn.vc]

Lync users:   Outbound/Inbound TCP Port 5061  - Lync Federation and SIP/TLS connection.    Outbound/Inbound UDP Ports   50000-59999  - RTP Media    Outbound/Inbound TCP Ports    50000-59999  - RTP Media

Please note: Some firewalls, such as Palo Alto Networks, prefer to filter network traffic based on the Fully Qualified Domain Name (FQDN). If this applies to your firewall configuration please use the following FQDN in order to connect to Blue Jeans: bjn.vc

Bandwidth Best Practices

Whenever possible users should have their ethernet hard lined into their device or connect on wifi (when on mobile). This will help stabilize the connection, especially at home or public areas. Our support team can help you gather your call quality stats and recommend improvements to further improve your on going Blue Jeans service. 

Guide for identifying and fixing insufficient call quality measurements: 
  1. Bandwidth: minimum of 384 Kbps, for both upload and download, is needed to support your video call. For 720p HD resolution the user should have at least 1024Kbps (1Mbps) up/down bandwidth as well as a 720p capable webcam.
  • To test the bandwidth from your network, click here. If your bandwidth results are insufficient, contact your broadband service provider (or your company IT engineer) and ask them what options they have available to increase your broadband capacity.
  • Jitter: Results above 40 ms can lead to poor video quality. Contact your IT engineer or broadband service provider if problem persists. 
  • Packet Loss: Results above 1% can lead to poor video quality. Contact your IT engineer or broadband service provider if problem persists.
  • Roundtrip: Results above 150 ms can lead to poor video quality. Contact your IT engineer or broadband service provider if problem persists.
  • SessionOut/In:
    • UDP - media packets are sent directly to remote side over UDP.
    • TCP - media packets are sent directly to remote side over TCP.
    • RELAY_UDP - media packets are sent to remote side over UDP, via relay node.
    • RELAY_TCP - media packets are sent to remote side over TCP, via relay node.
    • If it's TCP or RELAY_TCP, it usually indicates UDP ports are being blocked by a firewall. Please click here for guidelines on UDP/TCP ports used by Blue Jeans Network.
