Ceros Desktop!

October 16th, 2009

Ceros Desktop Edition

Ceros Desktop Edition

We are currently taking pre-orders for the Ceros Desktop, slated to ship November 1st, 2009. This unit measures in at an ultra-compact 8.5″ wide by 10″ long and 3″ tall — smaller than a ream of paper! The Ceros Desktop was designed specially  for users who need a powerful processing solution but don’t require a massive, power-hungry server.

The Ceros Desktop’s small size and low power usage make it an ideal solution for many situations, such as SOHO offices, satellite or remote offices, any many others. It’s best suited for installations up to 25-50 users, though its computing power can handle many more. The unit is powered by a compact 12VDC power supply which makes this an ideal mobile solution as well as keeping power usage and heat to a minimum. The unit has space for up to two short form factor PCI cards and can handle up to 16 analog channels FXO or FXS using two R8FXX-EC modular cards or up to 24 Analog FXO or FXS channels through use of a R1T1 card and channel bank combination. By combining these cards with any standard short from-factor PCI card and the flexibility of VoIP, the Ceros Desktop can fit your needs, whatever they may be. The Ceros Desktop can be your primary PBX or a remote connection back to your main site. Unlike other compact solutions, the Ceros Desktop is built in the spirit of its Ceros cousins. Designed and built in the USA with pride, its steel chassis and quality components will long outlast the competition’s cookie-cutter plastic box from Taiwan or China. The Ceros Desktop runs a standard Intel x86 processor making it compatible with any PBX or Linux distribution (or most anything else) you wish to use. It’s the perfect, open hardware server, whether you need to replace a  group of fax machines, extend some remote POTS lines with a VoIP trunk to your main office, or you just need a compact PBX for your business. Whatever your need the Ceros Desktop is ready for business.

Rhino Ships First PBX in a Flash Ceros

April 23rd, 2008


In keeping with Rhino’s goal to be OPEN and part of the community, we announced back in January that we would start shipping a multitude of Asterisk based distributions. Today Rhino shipped out our first Ceros with PBX in a Flash.

Pbx in a flash entered into the game not too long ago built by Joe Roper and distributed by Ward Mundy of Nerd Vittles. The distribution has gained a foothold and a following that is based on the fans of Ward Mundy and his Asterisk scripts. The First PBX in a Flash Ceros is on its Way to Oregon and we hope there will be many more shipping. You may also notice that this isn’t the Ceros you may be familiar with. After months of design changes the Ceros has been given an extreme makeover. Keep an eye out for the Official announcement of the new, more attractive Ceros.

FreePBX Training

March 3rd, 2008

I just got back after spending two days in beautiful Charleston, SC. at the FreePBX training event. I met many great people from the community and other industry suppliers such as Aastra and Snom. I met David (CEO) of Sangoma and Jared (Community Relations Manager) from Digium. There were quite a few other folks you may know like Robert Keller, Greg MacLellan (FreePBX), Philipe (FreePBX), Tony and Ethan (Scmoozecom), Joe Roper (PBX in a Flash and A2Billing), and so many more great people. Just meeting our friends in theindustry was fun enough, the training was the bonus. There was much covered in the training sessions, and I personally spoke on the subject of “T1″. Rhino gave away some door prizes (boards) and overall, with this being the first training session for FreePBX, I give this event a 9 out of a possible 10. I imagine that the next one will be off the charts, and I recommend to anyone that wants FreePBX training with emphasis on marketing Asterisk to your customers to attend this great event. I hear that the next one will be on the West Coast, perhaps Las Vegas. I have attached some photos from the event. Rhino is a proud member of the community and is a proud sponsor and participant of these community events.

trixbox 2.4 kernel-pae

January 26th, 2008

If Anaconda (the CentOS installer) detects a PAE compatible processor it will install kernel and kernel-pae

kernel-PAE (x86-only): Contains a kernel with support for 64GB of memory on x86 systems through Physical Address Extensions (PAE). Only x86 CPUs that support PAE can run this kernel. This kernel is provided because x86 systems can’t address more than 4GB of memory without PAE extensions.

trixbox is package based and everything wraps around modules in a specific kernel.

If your system gets the pae kernel you can correct this by editing /etc/grub.conf

you should see something to the effect of :
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

title trixbox (2.6.18-53.1.4.el5PAE)
root (hd0,0)
kernel /vmlinuz-2.6.18-53.1.4.el5PAE ro root=LABEL=/1 acpi=off
initrd /initrd-2.6.18-53.1.4.el5PAE.img
title trixbox-base (2.6.18-53.1.4.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-53.1.4.el5 ro root=LABEL=/1 acpi=off
initrd /initrd-2.6.18-53.1.4.el5.img

Simply use # to comment out:
#title trixbox (2.6.18-53.1.4.el5PAE)
#root (hd0,0)
#kernel /vmlinuz-2.6.18-53.1.4.el5PAE ro root=LABEL=/1 acpi=off
#initrd /initrd-2.6.18-53.1.4.el5PAE.img

Now you can ensure it will boot to the correct image.
