These holidays I got an observation from one of my customers. His carrier claims that PDD was variable with some 6-second peaks. Although 6 seconds I believe it is not that critical, it is in the annoying area. Usually, 3-4 seconds are acceptable.
First, I will define what is PDD. From: NICC ND 1704 V1.2.2 2009-05 End-to-End Network Performance Rules & Objectives for the Interconnection of NGNs
For SIP the PDD would be the time from Sending the INVITE to receiving the first ringing response for example: an SIP/2.0 180 Ringing response.
As a Chrismas present, I have published in OKay's RPM repository RPMs for FusionPBX 4.2.1. FusionPBX is an open source FreeSWITCH GUI. FusionPBX can be used as a high available single or domain based multi-tenant PBX, carrier-grade switch, call center server, fax server, VoIP server, voicemail server, conference server, voice application server, appliance framework and more. FreeSWITCHtm is a highly scalable, multi-threaded, multi-platform communication platform. FusionPBX license is the MPL 1.1 license.
This is a vanilla FusionPBX without any patch added from my part. I will add them later. This RPM will install MySQL (for CentOS 6) or MariaDB (for Centos 7) as the database backend, all possible information will be stored there, such as dial plans, profile information, registrations and so on. Installation is already configured as multi-tenant. Default username is superadmin (with same password), so please change it as soon as you get it installed. Database is optimized with many indexes that are not included if you install directly from the source.
As a premium add-on, installation using this RPM includes the LCR and Billing for FusionPBX in-app. You just need to activate it and start configuring.
RPM's are available for Centos 6 and 7. And you can find it if you type yum search fusionpbx.
It is very true that as a migrant, one of the first and greatest cultural shocks is having a resume that calls Human Resources attention. You will find as I did that they are like divas, even if you are over-qualified and asking for much less money than expected, you may be ignored if your resume does not fit the criteria. HR people are lazy, they will not read long resumes instead, they just scan for the keywords someone told them. Another thing you will find odd is that in Canada, at least, you will need to do a specific resume for each position you want to apply. A general resume will not give you the results you are looking for.
Fortunately for me and for many of you (if you follow my blog), I have found two books that I couldn't help it when I read the title. The one I will talk about is the third edition of the Best Canadian Résués from Sharon Graham. I will put here some notes and texts from the book.
Today I have published in OKay's RPM repository RPMs for FreeSWITCH 1.6.13. FreeSWITCH is a complete VoIP switch that works on many platforms, including Centos 6 and Centos 7. This is one of the biggest packages I have ever done; there are more than 1720 hours of work behind to make it work (mainly because the CentOS 6 support). When updating, you will notice it will download many libraries, most part of them not available anywhere.
The big difference on my RPM's is there are more sub-packages, for example, you can install only freeswitch-cli if you only need fs_cli command; Centos 6 RPMS for 32 and 64 bits are available with video support; I have imported a patch that fixes mod_nibblebill, in some situations leg b won't hang up and it will produce money losses. I have been updating some other dependencies such as VLC and MPG123 with latest stable if you were using my RPM's you will notice more updates as well.
Because libyuv is now part of the core, these RPMs are compiled with video support. Yes, you read it well, both Centos 6 and 7 with video support.
For those asking about FreeSWITCH changelog, this is the list published by them:
New features and improvements that were added:
Improvements in build system, cross platform support, and packaging:
The following bugs were squashed:
RPM's are available for Centos 6 and 7. And you can find it if you type yum search freeswitch.
In my last work change, I hired a Certified Immigration Consultant to do this. As I am Mexican and my profession is included in the NAFTA, I am a candidate for an LMIA (former LMO) exception. This means the employer effort is minimum. I will put here the documents he prepared. Please not I am not a lawyer, I just sharing with you what happened to me.
Memcache has proven to be an excellent option not only for caching but sharing information. One of the best use case scenarios I can think right away is with High Availability and Load Balancing. Wit HA and LB you don't have a certitude what server is serving, there sharing information with Memcache is the best way to have session information shared.
I will discuss here how to set it up using CentOS 6 and 7. You might figure out correct paths for your own distribution.
