that radio was designed for use with echolink.
And that can be pretty private if you limit connections to specific stations.
If you don't like that, maybe teamspeak.

A quick run down of available linking technologies in general...
Echolink
- Radio oriented
- Windows only software for "SysOp" mode
- Not able to link without access to the public internet and by going through their servers
- Public nodes often get numerous connections, referred to as drive-bys, with nothing said by the station. You end up hearing "Connecting..." and "Disconnecting..." messages in short order
- A majority of nodes are not set up properly with issues ranging from over/under-deviated audio to propagating all repeater output to connected stations including courtesy tones, IDs, announcements even when not using an over the air link to the system.
TeamSpeak
- Not radio oriented, no provisions for direct interfacing
- Separate out of band signaling required for PTT/COR, time lag between voice frames and control data not synced
- Ability to run independent of Internet on private LAN/WLAN
- Miscellaneous other features that might add value
- Multiple OS support
IRLP
- Proprietary radio oriented system, single source of hardware
- No connections allowed to/from other linking systems
- Internet dependent?
- Linux only
Asterisk
- Open-source PBX telephone system
- Several developers with amateur radio background
- Radio oriented module, app_rpt
- Ability to interface with equipment from simplex base up to full duplex repeater
- Can act as entire repeater controller
- Several interfacing options including DIY modified USB sound cards, commercially produced USB sound cards, and commercially produced boards
- Capability for voting and simulcasting radio networks
- Ability to link when one or more locations are behind a firewall such as cell-based mobile nodes
- No internet required
- On a single server both phone PBX and radio systems can run independently or with configurable interconnections
- Multiple network layouts are able to be used from single nodes on individual servers to multiple nodes on one server linked to several more on one or more additional servers
- Linux only
- Can connect to Echolink, capable of connecting to IRLP but that function was removed at the request of the IRLP owner
- You can be a part of the growing AllStarLink network
- The list goes on....
I would suggest looking into Asterisk/app_rpt. There is somewhat of a learning curve, especially if you are new to Linux, but the possibilities really are endless.
I tried to cover everything but I appologize if a missed something.
Hope that helps you be more informed.
A couple of points here. thelinkbox and SvxLink exist as Sysop Node options for Linux and MacOS, and QTel (part of SvxLink: is an available client for those platforms, but it requires port forwarding to work. The "drive-by connects" can be dealt for the most part by limiting the stations that are allowed to connect; audio issues are a stickier issue, as that is something that most people don't bother fixing, especially the link audio issues you mentioned.
IRLP Experimental Nodes can be connected to AllStar Link via the rtp-dir channel driver, but the IRLP channel driver was removed as you mentioned.
I added my 3 cents; and if anyone wants to get in touch with me via Radio over IP, I can be reached at Echolink Node 749507, AllStar Link node 28913 or D-STAR DExtra Reflector XRF669 A.
