This parameter was initialing defined in RFC4145, which has been updated by RFC4572. Zulu is a free Virtual DJ software. Those candidates are obtained from a TURN server which must be provisioned when creating the peer connection. Enter the Fully Qualified Domain Name of your server which you will be connecting to that matches the FQDN used with your SSL certificate you setup on your PBX. Install on MacOS. m means it is a media line – it condenses a lot of information on the media attributes of the stream. Using the Zulu 3 clients requires the installation of Zulu Server 3. If you are already getting a certificate error on Android, please see Android - Trust anchor for certification path not found for more information on how to resolve. There’s no need for a public IP, because you’ll connect behind your NAT without having to pass through the public internet. When you obtained Zulu UC licenses, you also received the same number of Connect licenses. The first number is the SSRC identifier that will be included in the SSRC field of the RTP packets. Payload numbers lower than 96 are mapped to encoding formats by the IANA. When they are both set to 0 like our case it means that the session is not bounded to a specific timing- in other words it’s permanent and valid at any time. Make/Receive phone calls directly from your laptop or desktop computer. No labels Overview. If you do define anything here, you almost certainly will NOT want to specify 'stunaddr' or 'turnaddr' above. Acceptable Use Policy | Terms of Service | Privacy Policy | Legal Terms for Telephone Services | Emergency Services Dialing – E911. This will happen when any parameter need to be changed in the media session such as on-hold, codec-change, add-remove media track. Google Android. The first number is the session id, an unique identifier for the session (2085624096). Running our own demo internally quickly helped us work out that it was in fact a code issue that was to blame. Use your FreePBX UC system to control your business IoT with through your phone. These candidates are discovered thanks to STUN server (see this. This fingerprint is the result of a hash function (using sha-256 in this case) of the certificates used in the DTLS-SRTP negotiation. Fully integrated with iOS and Android devices, your mobile office extension. However, when you are about to debug SIP packets through Asterisk on a busy system you will shortly realize that it's near impossible to differentiate the SIP packets because they all come from and go to the same source address: 127.0.0.1. You will need a license to run the Zulu 3 on FreePBX, if you don't already have one. ICE is the protocol chosen for NAT traversal in WebRTC. At this point Asterisk is running, PJSIP modules are loaded and ws/wss transports are bound, which you can confirm with: If the above gives an error instead of the transports shown above, then there is still an issue with enabling PJSIP. Changing this setting to "Yes" tells the Zulu client to connect to Asterisk directly, bypassing the Zulu proxy, you can then set logging through Asterisk for specifically your IP address. This page describes how to install and use Zulu 3 Softphone/UC client with FreePBX and PBXact, on macOS or Windows.. For information about the Connect Mobile softphone app for FreePBX and PBXact, on iOS and Android, see the Sangoma Connect wiki space. If the client acquires its IP, it’ll send a SRFLX candidate to the peer. Or use the QR Code feature from within the end user UCP panel of PBXact or FreePBX. The first lines (component= 1) is for RTP and second line (component = 2) is for RTCP. These lines specify G711 mu and a-law, which is a classic telecom 64kbps pulse code modulation (PCM) codec using different companding laws. This line creates a binding between the signaling (which is supposed to be trusted) and the certificates used in DTLS, if the fingerprint doesn’t match, then the session should be rejected. To use Zulu Mobile, please configure a valid certificate in the Certificate Manager, using the instructions in the Certificate Management User Guide. Markham ON L3R 9R6 CANADA. Reflexive candidate for RTCP over UDP - here we have the server reflexive candidates. Contacts module need to be enabled for Zulu 3.0 to work properly. Bypassing the Zulu proxy only helps with the debugging process. There are three different types of ICE candidate: Host candidates are for same-network connections. Some incoming call notifications were not being properly processed. Zulu Desktop and Zulu Mobile clients are very easy to install allowing end users to get connected immediately. Bypassing the Zulu proxy only helps with the debugging process. This is a necessary process if, for some reason, a direct peer-to-peer connection cannot be established between the two machines. An allocation returns the public IP in its response, so this is the client’s second chance to receive this. Then restart Asterisk and do the same test again to confirm PJSIP is loaded and ws/wss transports are enabled. The first number is the session id, an unique identifier for the session (2276445737850684162). I cannot make Zulu Mobile to work on my android phone. Just click or highlight a phone number on any web page and call it. In a few moments you will see that list being sent to Asterisk so that Asterisk can determine what candidates it wants to use. Reviews Review Policy. Some incoming call notifications were not being properly processed. Read the Zulu Bible free, can switch between of 57 languages of Bible, include Bible, Verses, Audios. When your machine makes requests to the internet, it sends a packet to a server via your NAT or router, including your local IP in the header. Double click on the Zulu-3.x.x.dmg file you downloaded. . SDP is a text based format. Search for Enable the Asterisk REST Interface and change it to YES, Search for SIP Channel Driver and change it to BOTH only if it's previously set to chan_sip. Receiving these on one side is not enough. This line is used to signal the association between the RTP concept of SSRC and the WebRTC concept of “media stream” / “media stream track” using SDP signaling [. Essentially, any means of getting a chunk of text data from client to peer and vice versa. This is useful to optimize the ICE process where a system has multiple host address ranges and/or physical interfaces and certain of them are not expected to be used for RTP. Looking at the SDP from Asterisk we can see there are only two candidates from Asterisk "fe80::290:27ff:feed:b7cc" and "192.168.1.4" these are being sent back to the Zulu client to use for audio routing. The client is the person who initiates the connection. Make/receive phone calls using your extension, Integrated into your mobile device’s native calling applications, Setup using your existing credentials or using the QR code feature within your UCP panel, Available on both iOS and Android devices. That allows you to use the Zulu UC desktop UC client described here, and the Connect Mobile apps.

Don't do that until AFTER we have figured out what the issue is. This is the identifier which is used in the BUNDLE line. This line defines extensions which will be used in RTP headers so that the receiver can decode it correctly and extract the metadata. These ids are handled in the WebRTC API. To receive support, please visit https://www.sangoma.com/support/. For more information about ICE candidates and the SDP (Session Description Protocol) format in general, take a look at The Anatomy of a WebRTC SDP over at WebRTCHacks, for an interactive breakdown. Likewise, there’s no need for TURN, because there will be no problem seeing peers on your own network. In certain networks, it's possible there may be a small audio delay (typically 3-4 seconds) from the time you answer an inbound call until the caller can hear you, {"serverDuration": 157, "requestCorrelationId": "c334534f4b6d67e7"}, https://portal.sangoma.com/index.php/store/displayStore, Everything revolves around the people you interact with. 31 total. STUN connections for Zulu are UDP only, so a failed attempt at this task will skip it entirely. Evaluate Confluence today.

Host candidate for RTP over TCP - These lines are the same as the two ICE lines before but for TCP traffic. Other values could be sendonly, recvonly and inactive which are used to implement different scenarios like putting calls on-hold. Now, if all you see are HOST candidates, then your application was never able to reach out to our servers to help establish a connection. The first parameter corresponds to the id of the Media Stream and the second onde the if of the Media Stream Track.
