Hi All,

Many thanks for the info, I am now finding the time to look back into
this again.

I have seen this page, which indicates that dahdi_pcap was pushed into
the dahdi driver from version 2.4.0;
https://issues.asterisk.org/jira/browse/DAHTOOL-49?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel

I have also seen this page regarding installing dahdi with dahdi_pcap;
http://lists.digium.com/pipermail/asterisk-ss7/2011-September/004519.html

All seems simple enough. I have no test systems with E1s/PRIs
connected. I have a particular production box though which is very
quite and I can schedule a maintenance window in which I can fiddle
with it. If I killed the box it's not really a problem as other boxes
can pick up the load. So my question is this;

Looking on this quiet box I see /usr/src/dahdi-linux-2.4.1.1 which
doesn't include dahdi_pcap. I am thinking of checking out the latest
version and compiling it to test dahdi_pcap. This box has Asterisk
11.3.0 running on Ubuntu Server 12.04.2 LTS.

If I re-route traffic away from this box (having never installed DAHDI
before) can I "simply" shutdown Asterisk, checkout the latest SVN,
compile, reload the kernel module and restart Asterisk?

What can go wrong here? Is this risky, or is it really that simple?

Cheers,
James,

The dahdi project moved from svn to git about a year ago. The existing
dahdi svn repo is stale and is for archival purposes only. Here is a
quickstart that should get you up and running with the dahdi git repo:

https://wiki.asterisk.org/wiki/display/DAHDI/Quick+Start+From+Source

You might want to skip the "dahdi_genconf system" step, as it will
overwrite your current /etc/dahdi/system.conf configuration.

Good luck!
