At 8:14 PM Eastern Time today we re-routed all calls destined for Haiti through Brazil.

We are now completing over 70% of calls into the country of Haiti and are assessing long term communications strategies for the coming days and weeks.

If there is anyone in need of calling Haiti, we can reserve a channel for you and try to get a call through.  We will try and get messages to family and friends in the event that we can not complete your call.  For more information, please send an email to haiti@vocaticommunications.com

The strongest earthquake in more than 200 years rocked Haiti on Tuesday, collapsing a hospital where people screamed for help and heavily damaging the National Palace, U.N. peacekeeper headquarters and other buildings. U.S. officials reported bodies in the streets and an aid official described “total disaster and chaos.”

United Nations officials said hours after the 7.0-magnitude quake struck at 4:53 p.m. that they still couldn’t account for a large number of U.N. personnel.

Communications were widely disrupted, making it impossible to get a full picture of damage as powerful aftershocks shook a desperately poor country where many buildings are flimsy. Electricity was out in some places.

Karel Zelenka, a Catholic Relief Services representative in Port-au-Prince, told U.S. colleagues before phone service failed that “there must be thousands of people dead,” according to a spokeswoman for the aid group, Sara Fajardo.

“He reported that it was just total disaster and chaos, that there were clouds of dust surrounding Port-au-Prince,” Fajardo said from the group’s offices in Maryland.

State Department spokesman P.J. Crowley said in Washington that U.S. Embassy personnel were “literally in the dark” after power failed.

Performance issues with A2Billing

Asterisk: optimizing a2billing mysql database with more than 1,000,000 rates in cc_ratecard

UPDATE: We just found out that the index we are talking about will be added to the next a2billing release. We have been told that the index is already part of the source repository now as of rev 2419.

Like many other people, we have experienced performance problems with a2billing ( asterisk2billing ) when our cc_ratecard table reached 1,000,000 rows.

We have surfed around the internet to find solutions to fix this problem. We found several solutions, some suggesting to split the cc_ratecard table into multiple tables in order to fix things. Nevertehless, we figured that there must be another way and there was indeed another way. Click below to read more…

Second, there is a missing index in the cc_ratecard that you can easily add yourself. This change alone will speed up things by a factor of about 10 from what we have found:

The column  idtariffplan (the one that could be moved to a separate table as mentioned above in our first point) in the cc_ratecard table doesn’t have any indexes.

Just add an index to this column to speed up things by a factor of around 10:

mysql>  create index idtariffplan_index on cc_ratecard (idtariffplan);

Et voila !!

Third make sure your mysql database itself is optimized for large tables. As example see the my.huge file content that is distributed with mysql  below.

A2billing is now running smootly with over 1,000,000 rates in cc_ratecard !

my-huge.cnf :

# Example MySQL config file for very large systems.
#
# This is for a large system with memory of 1G-2G where the system runs mainly
# MySQL.
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /var/lib/mysql) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the “–help” option.

# The following options will be passed to all MySQL clients

# Replication Master Server (default)

# but will not function as a master if omitted

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master’s port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST=’125.564.12.1′, MASTER_PORT=3306,
#    MASTER_USER=’joe’, MASTER_PASSWORD=’secret’;
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables’ values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 – 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave – required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master – required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master – required
#master-password =   <password>
#
# The port the master is listening on.
# optional – defaults to 3306
#master-port     =  <port>
#
# binary logging – not required for slaves, but recommended

Here is the text from the page:

Bill McCarthy, CEO of Vocati Communications Conversation

It’s one of the most common refrains among today’s telephony enthusiasts: VoIP can drastically increase savings and cut operating costs. But is the hype to be believed? According to Colin Taylor, CEO of contact-center consultancy The Taylor Reach Group Inc., while it’s true that most companies can expect a financial return on a VoIP investment, the metrics justifying the acquisition of an IP telephony system are quickly changing.

XO Carries Over 2 Billion Minutes in Q4

XO announced today that they carried over 2 billion minutes of VoIP traffic in Q4 of 2005, which was an increase of 22% over previous quarter.

YAWN!

Frankly, who cares how much network utilization XO has?  The metric is all wrong.  XO investors should care about the number of subscribers, and the dollars earned per subscriber.  Per minute revenues are trending to zero and the service is starting to suffer.  Announcing that the number of minutes carried has increased is like a cable company announcing that the number of bits carried has increased.  What  investors really want to know is revenue per subscriber.

And customers should care about SERVICE!  What happened to the days when you can pick up the phone and get great SERVICE?
