Multiple private nodes - rxchannel config

I will preface with the fact that most of my stuff is online and public as are the other stations I refer to here. That said… I am trying to experiment with exploring private nodes and static connections. I setup a private node [1999] with IAX only access for my brother to call me on, it works great… Next I want to have my dad’s private number [1957] connected all the time static to my [1999] node. I think I understand about mapping the ip addresses in both rpt.conf files.

The first (and hopefully only) issue I am having is the rxchannel configuration. You see my first private node [1999] is using rxchannel = USRP/127.0.0.1:34001:32001 and my public node [42177] is using rxchannel = dahdi/pseudo. This particular server is in the cloud, so no usb audio is used.

So what should I assign to node [1957] to avoid conflict or errors?

What interface do you want to use for 1957 and what conflict is of concern?

Whichever would work the simplest. LOL

I am very happy with the results of USRP and Dhadi both, but don’t know if I can simply add a digit at the end of the channel name like a suffix and that be sufficient, such as dhadi/pseudo2. Would there be conflicts? If I were to do this where all would I need to add it besides rpt.conf? What happens if I receive on both nodes at the same time? I guess the conflict I am worried about is a port conflict. With USRP I could define a different range it seems, but in modules.conf there is only one module for usrp, so I would need to add another correct?

You can have multiple nodes with rxchannel=dahdi/pseudo. Here’s an example from one of my servers. Note 25330 and 40501:

root@PBX:/etc/asterisk# grep -3 rxchan rpt.conf
;
[2522]                              ; Test Node
                                
rxchannel = Voter/2522              ; Rx audio/signalling channel
;rxchannel = Zap/pseudo             ; Rx audio/signalling channel
duplex=2
erxgain=-3                          ; Echolink receive gain adjustment
                                    ; Note: Gain is in db-volts (20logVI/VO)
--

[25330]                              ; Echolink
                                
rxchannel=DAHDI/pseudo              ; Rx audio/signalling channel
erxgain=-3                          ; Echolink receive gain adjustment
                                    ; Note: Gain is in db-volts (20logVI/VO)
etxgain=3                           ; Echolink transmit gain adjustment
--

[40501]                              ; Echolink
                                
rxchannel=DAHDI/pseudo              ; Rx audio/signalling channel
erxgain=-3                          ; Echolink receive gain adjustment
                                    ; Note: Gain is in db-volts (20logVI/VO)
etxgain=3                           ; Echolink transmit gain adjustment
root@PBX:/etc/asterisk#

I will go for it, much easier than I thought. Thank you for sharing!
