CentOS 5 Official Support Closure

As previously advised in the ScopServ blogs and ScopNEWS, CentOS 5 has now officially reached its End Of Life date. As a result, CentOS has officially shutdown their official repositories for CentOS EL5.

From now, if you are updating your existing ScopTEL EL5 packages this may cause errors similar to the following:

[root@pstn ~]# scopserv_yum update

==== scopserv_yum ====

This does not mean your installation is broken, it simply means that the official CentOS EL5 mirrors have been shut down. ScopServ has released a new scopserv-server package that uses vault.centos.org to maintain existing dependencies.  This package will be automatically installed via scopserv_yum update and if the scopserv-server package is updated you will not see this error the next time you do scopserv_yum update.

Here are the options to resolve the error (pick one):

  1. Update your packages using the ScopTEL GUI
  2. From a bash prompt execute ‘scopserv_yum update’ (omitting quotes)
  3. ‘rpm –Uvh http://download.scopserv.com/dist/packages/scopserv-server/scopserv-server-5.1.6.11.20170601-1.nodist.scopserv.noarch.rpm’ (omitting quotes)

Since CentOS 5 is officially End Of Life ScopServ highly recommends that you upgrade your installation to CentOS 6.

A failure to do so will put your installation at risk since CentOS EL5 is no longer supported.

Please follow the official instructions to upgrade your installation at

https://blog.scopserv.com/2016/12/scoptel-centos-6-x-bootdisk-installation-guide/

ScopServ will not be responsible for any liabilities caused by a failure to upgrade to a supported Operating System.  Additionally, ScopServ will be announcing an End Of Life date for ScopServ EL5 packages and support in the near future.

Avertissement Produit – Migration obligatoire du journal des files d’attente suite à la mise à jour de ‘scopserv-reports’ et ‘scopserv-realtime’ de la version 5 à la version 6 

Très Important

  • Les paquetages ‘scopserv-reports’ et ‘scopserv-realtime’ version 5 utilisent une méthode de transport plus ancienne et un fichier texte queue_log pour générer des rapports téléphoniques alors que ceux de version 6 sont hautement optimisés; nouveau transport par WebSockets et traitement des données ACD dans des tables SQL.
  • Mettre à jour les paquetages ‘scoperv-reports’ et ‘scopserv-realtime’ de version 5 vers la version 6 nécessitera l’exécution manuelle d’un script de migration du journal des files d’attentes sinon les nouvelles données pourraient ne pas être traitées.
  • Référez-vous immédiatement au bulletin ci-dessous avant la mise à jour des paquetages ‘scopserv-reports’ et ‘scopserv-realtime’ prévue le 31 janvier 2017.
  • Il est fortement recommandé de redémarrer votre serveur afin d’éviter des fuites de mémoire après avoir effectué une mise à jour des paquetages!

ScopTEL Version 5 to Version 6 scopserv-reports scopserv-realtime post upgrade mandatory Queue Log Migration Product Bulletin

  • Importance HIGH!
  • Official Release date is January 31st 2017
  • ScopServ scoptel-reports and scoptel-realtime release 5 packages use an older transport method and a flat queue_log file to generate Telephony Reports while the release 6 versions are highly optimized using a new WebSockets Transport and process raw ACD data to SQL tables.
  • Upgrading scoperv-reports and scopserv-realtime release 5 packages to release 6 scopserv-reports and scopserv-realtime packages will require you to manually execute the Queue Log Migration script else post upgrade reporting data will not be processed!
  • Please refer immediately to the this official Product Bulletin prior to the scopserv-reports and scopserv-realtime packages release date scheduled for January 15th 2017.
  • It is highly recommended you reboot your server to kill processes which might leak memory after updating the packages!

Product Bulletin: CVE-2015-0235 Ghost Vulnerability

Details:

https://rhn.redhat.com/errata/RHSA-2015-0090.html
Updated glibc packages that fix one security issue are now available for ScopServ Distributions built on CentOS 5.
Red Hat Product Security has rated this update as having Critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system.  Without these libraries, the Linux system cannot function correctly.
A heap-based buffer overflow was found in glibc’s __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls.  A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. (CVE-2015-0235)

Immediate Recommendations:

In order to protect your server and at the earliest convenience:
From the Linux shell execute (without quotations):

‘scopserv_yum update glibc* -y’

Ensure all updates have completed and then execute (without quotations)

‘reboot’

The minimum package requirements are:

glibc-devel-2.5-123
glibc-2.5-123
glibc-headers-2.5-123
glibc-2.5-123
glibc-common-2.5-123
nscd-2.5-123

ScopTEL RTP ‘directmedia’ Handling

What is directmedia?

  • When SIP initiates the call, the INVITE message contains the information on where to send the media streams. ScopTEL uses itself as the end-points of media streams when setting up the call. Once the call has been accepted, ScopTEL sends another re-INVITE message to the clients with the information necessary to have the two clients send the media streams directly to each other.
  • The ‘Can Reinvite’ option is used to enable directmedia options per peer in the ScopTEL GUI

Directmedia/re-INVITE Overview

  • When SIP endpoints communicate by way of ScopTEL, ScopTEL will attempt to send SIP re-INVITES in order to allow the endpoints to communicate directly. This allows for the computational load on the ScopTEL server to be decreased while also lessening the latency of the media streams between the endpoints.

How to Configure Server to Server SIP Trunking

Server to server SIP trunks are very useful and easy to configure.

DNIS is used to send and receive calls between servers

Usage Cases Implementing DNIS:

  • SIP TIE trunks:
    • A private network is created to dial extensions between systems using Access Codes
  • Tandem Dialing:
    • PSTN resources available to a remote server are shared to the local server
  • PSTN re-routing to a networked ScopTEL Server
