011306 InformaCast® Enabled Indoor Intercom - Flush Mount (Replacement Products are 011309 and 011443)

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.

Go to the Downloads tab, click on the serial number range matching your device and download the firmware compatible with it. V3 Firmware is not backwards compatible. Please contact VoIP Technical Support for assistance before attempting a firmware upgrade on a Pre-V3 device. To load the firmware from your PC, see your Operations Guide.

See SIP Point-To-Point Configuration

If the relay test button is working, the problem may result from interfacing with the IP phone where the DTMF tone is generated. To resolve this problem, please verify that the DTMF tone on the phone is set to out-of-band.

Make sure your SIP phone is set to 101 for the DTMF payload type (Out of Band RFC2833).

This is a common problem when the re-registration time value is not set correctly. On our device, you need to make sure that the re-registration time value (in minutes) is less than that is set on the IP-PBX server.

In the PBX setup page for the extension of the CyberData device, find the Qualify= value and change it to NO. If the Qualify= value requires a numeric value, then change it to 0. Note that on some Asterisk systems (such as Intuitive Voice) this value is called the Heartbeat= value. Set the Heartbeat= value to NO, and then save the settings. Also, on the product's SIP Setup page, make sure that the Register Expiration (minutes) setting is set to less than 6 minutes (5 minutes is good) because it needs to be a value less than the Asterisk default value of 6 minutes. Save the settings after changing the Register Expiration (minutes) setting.

RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz. You can use the free utility 'Audacity' (https://audacity.sourceforge.net/) to convert audio files into a format the device can recognize. When you export an audio file with this program, you can save the output as "WAV (Microsoft) signed 16 bit PCM."

You can enter the desired device name (such as ?Door Intercom? [up to 25 Characters]) into the Extension ID field on the SIP Config web page.

To guard against failed firmware upgrades, units shipped from CyberData with v5.1.2 feature a built-in "fail safe" mechanism. Note that field upgrading earlier units with v5.x.x will not allow for this feature. The Intercom will store the "TFTP Server IP" and "New Filename" entered on the "Update Firmware" web page. If, during the boot process, the Intercom is unable to boot the firmware, it will attempt to download the stored image from the stored TFTP server.

This High PIV Ultra Fast switching diode prevents CEMF kick back from an intermediary relay coil when power is cut and the coil field collapses. You could use an On-Semi MUR105 diode.

This happens because with default settings, the switch port is resetting power too quickly. Therefore, on the 3550 switch, on the switch port that the unit is attached to, please try adding the following CLI command: power inline delay shutdown 20 initial 300. That should keep power supplied until the unit can boot up all the way.

If connected to a Linksys SRW208MP switch, the CyberData device stays up. Pantel, Cisco, or Linksys PoE endpoints all work on the Dell Powerconnect 3524P. A user tried hard coding the switch speed/duplex and tried four different Dell Powerconnect 3524P switches. Check to make sure the Dell Powerconnect 3524P has flow control enabled on the port for the CyberData device to power up properly. According to Dell: Flow Control Support (IEEE 802.3X): Flow control enables lower speed devices to communicate with higher speed devices by requesting that the higher speed device refrains from sending packets. Transmissions are temporarily halted to prevent buffer overflows. For information on configuring Flow Control for ports or LAGs, see "Defining Port Configuration" or "Defining LAG Parameters" in the Dell PowerConnect 35xx Systems User's Guide.

The cables or switch ports that you are connecting to are set in switch or hub mode instead of endpoint stations. The MDIX setting needs to be changed to MDI since our VoIP products are end stations. From the Cisco SLM 224P User Guide:

Change to MDI: MDI/MDIX displays the Media Dependent Interface (MDI) / Media Dependent Interface with Crossover (MDIX) status on the port. Hubs and switches are deliberately wired the opposite of the way end stations are wired, so that when a hub or switch is connected to an end station, a straight through Ethernet cable can be used, and the pairs are matched up properly. When two hubs or switches are connected to each other, or two end stations are connected to each other, a crossover cable is used to ensure that the correct pairs are connected. The possible field values are: MDIX

Use for hubs and switches. MDI Use for end stations.

Please adjust the switch power selection to Power inline static, as opposed to Power inline dynamic. This will allow the device to continuously receive 15.4W of power.

The filename can be shortened but must include "uImage" in the filename. Be sure to note that uImage has an "I" and not a "1".

Create a second directory number and user for the Nightringer extension. You may need to fudge a digit of the MAC Address so that Call Manager allows you to associate it to the new user. Be sure this MAC address does not match any other CyberData devices on your network.

There are known PoE limitations with third party devices on the Cisco Catalyst series switches. This includes the 2500, 3500, and 6500 series switches. It's important to keep in mind that CyberData devices are considered third party devices and require switch port setting adjustments. Be sure to turn power policing off if it has been enabled on your switch. Power policing is disabled by default. Also, configure your port for no shutdown. Use the following command to configure inline power: power inline static max 15400.

The average Intercom volume level is 9 SPL using the standard 1KHz test tone normalized at 0dB and yields 93dB output at 1 meter.

Be sure to refer to the Installation Quick Reference Guide for wall mounting or gang box mounting installation options. The intercom must be electrically grounded. This will prevent static electricity from interfering with the intercom operation or damaging the unit.
