FAQs How do I update my firmware? Go to the Downloads tab, click on the serial number range matching your device and download the firmware compatible with it. To update the firmware, unzip the file and log in to the web GUI for the device you are trying to upgrade. Navigate to the Firmware tab and browse for the firmware file you just downloaded. Select and upload that file. Do not reboot, the device will do it for you. For more information, please check your product’s Operations Guide, also available under the Downloads tab. Is this device compatible with my service provider or IP-PBX server? CyberData VoIP products are compatible with IP-PBX servers that support standard SIP protocol. You can find a full list of IP-PBX servers that CyberData products have been validated on by going to Connecting to Compatible IP-PBX Servers. If you do not see your IP-PBX on this list, feel free to contact CyberData’s Technical Support Department for more information. What is multicast? IP multicast is a technique for one-to-many communication over a local IP network. IGMP multicast is sent via UDP packets from a multicast server to a multicast receiver. This stream scales to a larger receiver population by not requiring prior knowledge of who or how many receivers there are. Multicast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to many receivers. The network replicates the packet in order to reach multiple receivers only when necessary. Multicast is a great alternative to SIP registration as it does not require that the recipient of the stream to register as an extension on an IP-PBX server. CyberData products support both regular IGMP multicast as well as proprietary Polycom Group Paging. How do I page to phones that can listen to Multicast? See the CyberData Technical Support Knowledgebase article providing documents How Do I Page to Phones That Can Listen to Multicast? How many Poly channels can the SIP Paging 25V/70V Amplifier page to? The SIP Paging 25V/70V Amplifier's page groups (PGroups) can be set to page to a specific channel. This allows for each PGroup to page to a different channel. How many zones does the SIP Paging 25/70 Amplifier support? One physical analog zone and 100 multicast based zones. Which is louder, 25V or 70V? Voltage selected for usage does not have an impact on loudness, the wattage selected per speaker determines loudness. How many speakers can be connected to a single SIP Paging 25/70 Amplifier? The number of speakers supported depends on the wattage total of the speakers. Will the SIP Paging 25V/70V Amplifier work with any speaker? Assuming the speaker is either 25V or 70V, yes. What wire gauge should be used with the SIP Paging 25V/70V Amplifier? CyberData recommends using 12 or 14 AWG when connecting to speakers. A thicker wire gauge can allow for a longer run length. For example, a 12 AWG wire can reach upwards of 3,000 feet when set to 70V mode. How should speakers be wired to the SIP Paging 25V/70V Amplifier? The speakers should be wired in a parallel fashion with a single connection to the SIP Paging 25V/70V Amplifier. Can it receive multicast? Yes, the SIP Paging 25V/70V Paging Amplifier can both Send and Receive Multicast. Can this be connected to an external amplifier? Yes, in a limited sense. The SIP Paging 25V/70V amplifier has a 10,000 Ohm unbalanced line level audio output that could be used with some analog amplifiers. This is located on pins 8 and 9 of the screw down terminal labeled Interface I/O. Can this be used with self-amplified speakers? Yes, the SIP Paging 25V/70V Amplifier can connect to self-amplified speakers using the line level output if it is connected to a device to isolate any back fed current from the amplifier on the speaker.
