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

Wed Jun 10 11:47:55 UTC 2015

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?
