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.

yum update -y

FYI all trixbox CE users

Just to give everyone a heads up from the Rhino’s mouth. Rhino products are proud to continually work with trixbox CE and future trixbox distributions. We also take great pride in our customers and realize that the more information that is posted the better informed we all are. That is why we take it very seriously to keep our customers informed of any ongoing issues with our hardware and distributions that we recommend.

The following issue has been popping up all over so please be aware of what you are installing at all times.

Please note that if you do a yum update for any of the following systems we cannot support your system until the system has been completely restored to factory settings.

trixbox CE 2.2

trixbox CE 2.2.1

trixbox CE 2.2.2

trixbox CE 2.2.3

trixbox CE 2.2.4

trixbox CE 2.2.5

trixbox CE 2.2.6

trixbox CE 2.2.7

trixbox CE 2.2.8

trixbox CE 2.2.9

This includes any future releases on the trixbox CE 2.2.x branch

This is due to errors in the trixbox repositories and this leads to corruption to your trixbox system.

The repositories for the upcoming trixbox 2.4 will be updated from what our trixbox sources have said, but for the trixbox 2.2.x repository this is not something that they can currently fix.

HDLC and FCS abort errors with Rhino T1/E1 Cards and PRI

Tuesday, November 20th, 2007

If you are seeing HDLC and FCS aborts in your logs. This is could be due to one of the following reasons:

1:

Make sure that your T1/E1 cards are at the following revisions and have the apropriate drivers installed on your system.

R1T1 -EC and Non-EC models must be at Hardware version 37 or above

R2T1 and R4T1 must be at Hardware version 36 or above

Driver revision must be at 2.0 and above.

If the above criteria is not met then you may see the aborts in your logs.

2:

If you are using CentOS4 and are using SATA drives you may see this issue.

You must use a kernel greater than 2.6.9.

By upgrading to an asterisk distribution with an updated kernel such as CentOS5 will alleviate these issues.

Please try one of the following systems:

Elastix

trixbox CE 2.4 (Beta for Cent 5)

RhinOSterisk (Alpha)

Configuring Your Rhino Digital Card For E1 Signalling

Friday, November 2nd, 2007

The basic principle is that we need set E1 mode at the driver level. There are no jumpers or any other physical changes that need to be made for Rhino OST PCI Digital Cards to work in E1 mode. Everything is done at the driver level.

1) Install the Digital PCI card into your server

If you are unclear on how to install your PCI card into your server please see the following documentation:

ftp://ftp.rhinoequipment.com/Documentation

2) Install the Rhino drivers

trixbox CE users please use an updated package that is located at ftp://ftp.rhinoequipment.com/Drivers/RPMS/trixbox/

All other distrobutions please use the package located at ftp://ftp.rhinoequipment.com/Drivers/Beta/rhino-2.2.1beta2.tbz2

3) Either insmod or modprobe with E1

NOTE: Make sure that the r1t1 or rxt1 drivers are not loaded when trying to switch to E1

insmod /lib/module/`uname -r`/extra/r1t1.ko e1=1

or you should be able to just modprobe with the settings

modprobe r1t1 e1=1

Generally you will need to have the modprobe r1t1 e1=1 in whatever file that you set to call the module on system start up.

If you are using an r1t1 then use:

modprobe r1t1 e1=1

For an r2t1 or r4t1 use:

modprobe rxt1 e1=15

4) Next, make sure that you now have 31 channels on your zaptel span

cat /proc/zaptel/*

5) Configuring of the card is now necassary, lets edit /etc/zaptel.conf

NOTE: This is just a generic view of what the zaptel.conf should look like

span=1,1,0,ccr,hdb3,crc4

(NOTE- the framing is dependent on what your carrier uses Rhino has no knowledge of what you should be specifically using for your telephony system)

bchan=1-15,17-31

dchan= 16

6) Now configure /etc/asterisk/zapata.conf or zapata-auto.conf or you may even be using zapata-channels.conf

signalling=pri_cpe

context=from-zaptel

channel=>1-15,17-31

7) Now define your trunks and dialing routes and test.

If you are still experiencing difficulties please contact Rhino Support immediately and we will get you setup right away!
