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

Wednesday, 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.

trixbox 2.4 kernel-pae

Saturday, 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.

FreePBX update

Thursday, January 24th, 2008

Just got word that 2 of the 4 scholarships are gone and from what I hear the Hotel is almost full so if you want to grab a discount you better make a run for it because it didnt take long to fill the 2 slots I imagine the other 2 will be gone in a day or so.

By the way I was watching American Idol ( I know shut-up) and they were in Charleston SC. And they did the little intro where they scrolled through the area and It looks like an awesome place to visit. I Like old buildings so definitely on my list.

EDIT as of 2PM 01/24 only 1 Rhino Seat remains

trixbox CE Privacy Notice!

Thursday, January 10th, 2008

Allot of ceros users are upgrading to trixbox 2.4 we do not recommend using any of the betas if your using a beta it would be best to push up to 2.4 stable.

In trixbox 2.4 betas and in 2.4 there is what trixbox calls a hardware audit tool also referenced to as a “phone home script”. (more…)

rhino drivers from source

Thursday, December 20th, 2007

trixbox2.3.0.10 (note 2.2 has rpms)
Centos 5 has some quirks which make compiling difficult. We hope to have an RPM out today but in the mean time I have written a few scripts to make compiling as painless as possible. Please note these steps require an internet connection that can do proper dns resolution

1. go to /usr/src
2. Download the scripts:
3. Make the scripts executable:
chmod +x *.sh
4. Find your zaptel version and run fakezap
modinfo zaptel #please note you only want the version not the build so 1.4.7-1234 is 1.4.7
./ -v 1.4.7 #replace 1.4.7 with the proper version
5. Build the drivers. our latest version is 2.2.2
./ -v 2.2.2
6. I recommend downloading our modprobe file
wget -O /etc/modprobe.d/modprobe.rhino

Elastix Now Supported!!!

Monday, December 17th, 2007

Rhino Equipment is pleased to announce the availability of Elastix on our Rhino Ceros line of equipment.

Elastix allows us to gain a stable platform that is fully compatible out of the box with modern hardware such as PCI Express and SATA. This allows for proper use of interrupt management features like ACPI. All of this without losing the PBX features you have come to love.

You also gain new features such as an integrated HylaFax server, Communications and more flexibility through the web UI.

This system has been fully tested and integrated into our Rhino Ceros product. We recommend the 2.6.18 and above kernel for boxes that contain multiple network cards, digital cards used in conjunction with other digital or analog cards, and PCI-E cards. This kernel is native to the Elastix distrobution.
