AirCodec · Connecting other codecs
Whatever is at the other end, there is a way in.
AirCodec speaks the standards rather than a private protocol, so most of the job is knowing which setting on the far-end box corresponds to which setting here. These pages are the cheat sheet, one piece of hardware at a time.
Comrex
Register the unit on the same account from Settings → Devices, give it a name, and type the server details it hands back into the codec. Then dial it by name from a connection profile. There is also an RTP preset that fills in what a Comrex expects when you would rather point straight at an address.
Needs EBU 3326 / SIP support, which the current BRIC units have
Tieline
Same path as a Comrex — register it as a device, get its name and credentials, and call it by name. Match the codec and bit rate on the connection profile, or let the caller state it and the Tieline accept.
Needs SIP enabled on the unit
RØDECaster Pro II & Duo
The CallMe channel on a RØDECaster will place and take SIP calls once the console has a CallMe Pro subscription on it. Full walkthrough below.
Needs CallMe Pro — SIP is not in the base CallMe feature
Anything else that speaks EBU 3326
If a box can register to a SIP server and negotiate Opus, G.722 or G.711, it can talk to AirCodec. Register it as a device, dial it by name, and pick a codec both ends support.
Needs nothing from us — no plug-in, no licence at the far end
A RØDECaster as the far end, over SIP
RØDE's CallMe channel started as a way to get a guest on a call. With a CallMe Pro subscription it becomes a SIP endpoint with third-party interoperability — which means AirCodec can dial it, and it can dial AirCodec. For a studio that already owns a RØDECaster Pro II or Duo, that is a remote rig you do not have to buy.
- Put CallMe Pro on the consolePlain CallMe does RØDECaster-to-RØDECaster and browser guests. SIP calling to anything else is the Pro tier only, so check the subscription before you plan a remote around it.
- Register the console as a device hereSettings → Devices in AirCodec. Give it a name — press-box-rode, say — press Register device, and the server hands back the address, port, transport, username, password and realm it needs.
- Enter those into the CallMe channelOn the console, select the CallMe channel and open CallMe Configuration. The SIP options take the address and the credentials, and let you pick the codec.
- Agree on a codecSet Opus if the path will carry it; G.722 if it will not. The caller states the codec and the far end either opens it or refuses, so the two ends have to be able to meet.
- Call either wayDial out from the console to AirCodec's endpoint name, or load a connection profile here pointing at the RØDECaster and press Connect. Set auto answer at whichever end nobody is sitting at.
What the RØDECaster brings
- Transport
- UDP, TCP or TLS
- Codecs
- Opus, G.722, G.711 and PCM — all of which AirCodec also runs
- Jitter buffer
- Adjustable on the console
- Answering
- Auto-answer and quick dials
- Channels
- Three CallMe channels for multiple guests
- Control
- Touchscreen, local web UI or CallMe Hub
Worth knowing before the show
- Incoming calls to the console can be blocked entirely with the Enable call hosting toggle in CallMe settings — handy, and easy to leave off by accident.
- RØDE's own guidance warns about public Wi-Fi for CallMe. A hotel or venue network is the usual reason a remote will not come up.
- The console is a mixer first. Decide which channel feeds the SIP leg before you are on air, not during.
From AirCodec's side, nothing is special about it. A RØDECaster registered on the account is an endpoint like any other — it appears in the list, it is dialled by name, and it shows up on the readouts grid and over SNMP with the same figures as a Comrex would. It can sit in a connection list as the 1st, 2nd or 3rd slot and be tested quietly like anything else.
Subscription tiers, transports and codecs above are as RØDE documents them for the RØDECaster Pro II and Duo. Check their support pages for the current feature set before specifying a job around it.

Got a box that is not on this list?
Tell us the make and model and we will work out whether it will talk to AirCodec — and if it will, we will write the walkthrough and put it on this page.
