[HSMM-COS] l-com, Tessco, and Asterisk

[Bill Bishop]

Hi guys,

  Here's the surge-supression hardware I picked up from l-com(.com):

  Elliot mentioned that Tessco was less expensive, but they want $50
(and up) for their type N (connector) microwave (3GHz) lightning
protectors, while l-com was $18 (and $5 for replacement gas discharge
tubes).    Tessco didn't appear to have any outdoor (weatherproof) data
(ethernet) protection devices.

 Free authoritative Asterisk books on-line:

4th Edition (current):

3rd Edition (most content is good):

  (.pdf's are easy to find)

Firewall Ports used:

  My /etc/asterisk/rtp.conf specifies ports 10,000 to 20,000 for RTP
(real-time protocol -- the voice data) -- the defaults.
  and the "usual" port 5060 for SIP signalling.

I have the hardcopy of both books;  I finished the 3rd edition a while
ago, and I'm about 1/4 of the way through the 4th edition.  I've looked
at the freePBX interface, but I've done everything with a text editor
(no guI).

Have a great weekend, everyone!
