In the Spring of 2019, Easy On Hold® was chosen by Cisco® to develop the only Cisco-supported solution for streaming live content into VVB for callers in queue. The solution, provided both in the cloud and on-premise, has been fully validated by Cisco® for use in VVB version 12.5.
"We are excited to offer this solution to telecom professionals seeking an alternative to static files," said Easy On Hold® CEO Julie Brown.
Beta testing is taking place at this time. If you would like to participate, please contact us.

The appliance is typically installed on-premise, on a LAN segment to be close to the VVB servers. The appliance maintains a live connection over the internet to a high quality https audio stream. That audio stream is locally transcoded and server to many local VVB clients, which received the audio as a decoded PCM stream.
Cloud-based streaming queue music is approved and best used for installations of up to 300 concurrent connections. For more than 500 concurrent connections (calls on hold) a premise based solution is available (VM Ware)
Frequently, Easy On Hold® receives requests for a streaming Cisco hold music solution. CUCM music on hold can now in the form of an rtp stream Call Manager can play.
Rather than playing a music on hold audio file as the default MOH source, CUCM can use a multicast IP address to stream content such as custom messages, legal music and even licensed hit music by popular artists. The new Easy On Hold® 2-Channel Business Audio System can be configured to output an rtp stream CUCM likes. Think of it as an rtp music server.
Note: Not available for CUCM version 10.5 (May, 2014) or earlier.
Because the CUCM multicast is a broadcast, the RTP stream provided by the EOH 2-C BAS can be a resource to play music and messages on any number of lines. Essentially, Easy On Hold® provides the end-user a music-control portal used to set content preferences. Then, an https .mp3 stream is integrated into the EOH 2-C BAS device on-premise. The EOH device transcodes the content to an rtp stream on an IP address for the CUCM to broadcast.
Cisco CUCM will not recognize a stream in http. Nor will it allow use of a streaming MOH source that is not hosted on its own network. Therefore, we mount a device on the Cisco network and let it do all the work of generating an acceptable RTP stream. The 2-C BAS device receives the stream from the EOH servers and broadcasts the rtp audio stream over the same, single ethernet connection.
All music on hold must be properly licensed, either through the appropriate Performing Rights Organization in your country, or a licensed provider, such as Easy On Hold®. Beware of your licensing liabilities before putting music on hold.
We identified the specific multicast group we were going to use for this application as a general pre-requisite before configuring CUCM. Next we configured an audio source in CUCM that leveraged the Sample Audio Source file but associated it to a new audio source ID (ID 2, in our setup). The reason we used a real audio source file is that if the media consumer (i.e.the device placed on hold) was not on a multicast network, we still wanted to send MoH. It would just be the Cisco sample audio source.
Audio Source Configuration
MoH Server Configuration
We only associate the multicast capabilities to one of the CUCM IPVMS nodes. This MoH server was configured as follows:
Media Resource Group
We create two media resource groups (MRGs). The MoH server is assigned to both MRGs. The only difference between the two is that one MRG is multicast enabled, while the other is not.
Media Resource Group List
We created at least two media resource group lists (MRGLs). One of these MRGLs contained the multicast-enabled MRG, while the other does not. The latter is assigned to devices on networks incapable of routing multicast, while the former is associated to devices that are on multicast-enabled networks.
Multicast may not be enabled across all the subnets on your Cisco system. Multicast must be enabled across the entire V-Lan or subnets in order for all locations to access the MOH stream. The 2CBAS appliance is basically presenting the RTP stream to the network in the form of an IP address, to offer MOH to virtual installations. If a soundcard is available, check with Cisco on the USB to audio connector that was popular before VM was commonplace.
