[App_rpt-users] use of an IP phone to monitor my node

Wed Jun 10 12:36:13 UTC 2015

Thanks Bill.

I did not knew about the web configuration of the phone, I was under the 
feeling I would have to program it from the small screen on it.. so that is 
a good news!

But as you said it, I wont open my sip port to the web..

I will try to understand how to make a trunk in IAX2 between my asterisk at 
home and the repeater site..

Anyone here could tell me what would be a good distro for such a small 
system at home?

I have a few thin client that could be used..

PIAF sound good.. I could use  a small ubs stick to run my stuff..

The HD in the Thin client is 1 GB the ram is 1GB  and the cpu speed is 1GHZ 
..

I took a look at the PFSENSE asterisk package. I run this as my router at 
home, the thing seem to be used by guys that knows a lot about asterisk.. I 
know some stuff. but not enough to venture in that game..

I've used several SIP VoIP phones to do exactly what you want...except my 
node is local to me so I deal only on the LAN side.  As an administrator of 
VoIP systems I'll caution opening up your remote node to SIP traffic as 
there are a lot of bad folks out there port scanning SIP 5060 all day long. 
One of our Asterisk systems was being hit so many times by people trying to 
register a SIP phone that we finally had to shut down remote SIP 
registration, by using ACLs in the phone system first but this didn't stop 
the traffic at the router so we dropped all SIP traffic there from the 
Internet.  A real shame because we had users who wanted to work at home and 
a remotely registered SIP phone would have been handy.

As to the Polycom 335, these are about the easiest SIP phones to set up on 
any VoIP system.  If you've done a factory reset then it will come up as 
DHCP and get an IP address from your LAN.  Once you discover the IP address 
it has (press MENU>STATUS>NETWORK>TCPIP) you can HTTP into the phone to set 
up the phone's extension and registration credentials, SIP port, NTP 
settings, digitmap, etc..  You may need to modify the digitmap as well, look 
for the SIP tab at the top of the web interface and scroll down to digitmap. 
If your first digit for extensions is a 5 and they are 4 digits in length, 
for example, be sure there is a setting at the beginning of the dial plan 
string that looks "5xxx|" or modify the default digitmap like "[0-8]xxx|" 
(leave off the quotes of course).

I've found it quite convenient to have a SIP phone on my LAN that is 
connected to my simplex node all the time.  Thanks to a local ham who knows 
app_rpt quite well I was able to set up the extension for my simplex node so 
I can just dial my node number and leave the phone connected all of the time 
on speakerphone (receive only).  I can monitor traffic, and if necessary use 
the phone in lieu of an HT to talk to folks using the "cop6" parameter in 
your RPT.CONF file to turn on transmit (*99 in my system), then dial a "#" 
to drop the transmit but keep the phone connected in receive-only mode.  Its 
kind of a pain to use this sequence as a PTT, so I also keep an HT around to 
RF into my node to talk.

Hope this was useful, enjoy!

#yiv7606176711 Thanks
that will be a start.. But this mean I need to open my sip
port to the internet cause my node is not here.. It is at
the repeater site..
or I am
thinking I could make myself a small asterisk server
(without app_rpt) and link that server to my node by
IAX?
