Instalando y configurando el CDR ODBC en Asterisk

Installing and Configuring ODBC

The ODBC connector is a database abstraction layer that makes it possible for Asterisk to communicate with a wide range of databases without requiring the developers to create a separate database connector for every database Asterisk wants to support. This saves a lot of development effort and code maintenance. There is a slight performance cost, because we are adding another application layer between Asterisk and the database, but this can be mitigated with proper design and is well worth it when you need powerful, flexible database capabilities in your Asterisk system.

Before you install the connector in Asterisk, you have to install ODBC into Linux itself. To install the ODBC drivers, use one of the following commands.

CISCO IP Phones 79XX con Asterisk

Recently we had a pack of cisco 7942G phones that we were required to get them up running with Asterisk. The good thing about 79XX series is that they all support SIP besides SCCP. Whereas, the bad thing is that they are by default running on SCCP and you have to upgrade them to SIP first. I spent a great deal of time trying to figure this out, as I were going to use SIP Version 8 and there is no to-the-point documentation (at least not that I could find!)

Here are the steps you need to get this up and running:

SIP Retransmissions

What is the problem with SIP retransmits?

Sometimes you get messages in the console like these:

retrans_pkt: Hanging up call XX77yy  - no reply to our critical packet. retrans_pkt: Cancelling retransmit of OPTIONs

The SIP protocol is based on requests and replies. Both sides send requests and wait for replies. Some of these requests are important. In a TCP/IP network many things can happen with IP packets. Firewalls, NAT devices, Session Border Controllers and SIP Proxys are in the signalling path and they will affect the call.

Asterisk for Raspberry Pi Image

I have installed vanilla Asterisk onto a Raspberry Pi and have created an image for all to use. The Asterisk install is not a bundalled install like raspbx which uses FreePBX. Asterisk is configured with all deafults straight from a new build/compile.
