ofonod: GNOME Calls backend over org.ofono for Phosh and GNOME Mobile
imsd-ofonod presents imsd on the system bus as an oFono modem — Manager at /, Modem + VoiceCallManager at /imsd, a VoiceCall object per call — which is what GNOME Calls' bundled ofono provider drives; Calls, Phosh and GNOME Shell run unmodified. org.gnome.Calls is not a seam a third party can provide (Calls exports it, nothing feeds it), and Calls' provider plugins link private headers, so org.ofono is the only D-Bus contract available. Pure GDBus translation of net.catcrafts.IMS1, no core, like imsd-dialerd. Packaged as the opt-in imsd-ofono subpackage: the daemon, its unit (Conflicts=ofono.service), the system-bus policy and a gschema override that points Calls at the ofono provider instead of mm (the ModemManager origin would offer the modem's CS voice path, which carries no audio on these phones). The policy grants root send_destination=org.ofono: under dbus-broker a broadcast is checked against the sender's send policy for every name the receiver owns, so without it imsd's call signals never reach the daemon. Verified on a Fairphone 6 with GNOME Calls 50.0: outgoing and incoming calls with audio both ways, answered and hung up through org.gnome.Calls.Call. Known Calls-side gap documented in the README: after the VoiceCallManager interface is withdrawn and re-added, Calls keeps the old origin's CallAdded handler and eventually crashes.

Phosh's own call UI needs nothing extra: it consumes `org.gnome.Calls`, which

||||
GNOME Calls exports once it has a working origin.

## GNOME Calls (Phosh, GNOME Mobile)
|
||||
|
||||
`imsd-ofonod` presents imsd on the system bus as an oFono modem — a Manager at
|
||||
`/`, one Modem + VoiceCallManager at `/imsd`, and a VoiceCall object per live
|
||||
call — which is what GNOME Calls' bundled `ofono` provider plugin drives.
|
||||
Calls, Phosh and GNOME Shell run unmodified.
|
||||
|
||||
`org.ofono` is the seam because it is the only one a third party can
|
||||
implement. `org.gnome.Calls.Call` is what Calls *exports* so a shell can
|
||||
observe and control a call that already exists (Accept, Hangup, SendDtmf,
|
||||
Silence — there is no Dial); Phosh consumes it from Calls. Calls' own backends
|
||||
are libpeas provider plugins (`mm`, `ofono`, `sip`, `dummy`) linked against
|
||||
private headers that no distro installs.
|
||||
|
||||
Setup:
|
||||
|
||||
```sh
|
||||
apk add imsd-ofono # or install the files by hand
|
||||
systemctl enable --now imsd-ofonod # system service; org.ofono is a system name
|
||||
# point Calls at the ofono provider (the package ships this as a gschema
|
||||
# override; this is the per-user equivalent)
|
||||
gsettings set org.gnome.Calls autoload-plugins "['ofono']"
|
||||
```
|
||||
|
||||
Drop `mm` from `autoload-plugins` rather than adding `ofono` alongside it: the
|
||||
ModemManager provider would offer the modem's own CS voice path as a second
|
||||
origin, and on a phone whose voice path is imsd that origin carries no audio.
|
||||
|
||||
Do not run this alongside a real `ofonod` — there is one `org.ofono` name and
|
||||
one owner; the unit declares `Conflicts=ofono.service` and the daemon exits if
|
||||
it loses the name. Running `imsd-dialerd` at the same time is fine (different
|
||||
bus, different consumer).
|
||||
|
||||
Verified on a Fairphone 6 (postmarketOS, dbus-broker) with GNOME Calls 50.0:
|
||||
outgoing and incoming calls with audio both ways, answered and hung up through
|
||||
`org.gnome.Calls.Call` — the surface Phosh drives. One dbus-broker detail is
|
||||
load-bearing and lives in the policy file: dbus-broker checks a broadcast
|
||||
against the sender's send policy for every name the receiver owns, so root
|
||||
(imsd) must be allowed `send_destination="org.ofono"` or imsd's call signals
|
||||
never reach the daemon.
|
||||
|
||||
Known gaps, all inherited rather than introduced:
|
||||
|
||||
- **USSD is refused** with `org.ofono.Error.NotSupported`; the IMS stack has no
|
||||
USSD path. It is deliberately not advertised in the modem's `Interfaces`.
|
||||
- **No hold, multiparty, transfer or call waiting** — imsd is a single-call
|
||||
stack, so those methods return `org.ofono.Error.NotImplemented`.
|
||||
- **Per-call caller-ID withholding is refused** rather than silently ignored:
|
||||
imsd cannot honour a CLIR request, and failing is safer than dialling with
|
||||
the caller ID exposed.
|
||||
- **Phosh's emergency-call screen lists nothing.** Not for want of the data:
|
||||
`imsd-ofonod` publishes `org.ofono.VoiceCallManager.EmergencyNumbers` (112,
|
||||
911, plus `EMERGENCY_NUMBERS`), which is oFono's standard place for it.
|
||||
Calls' ofono provider simply never reads it — it makes no `GetProperties`
|
||||
call on the VoiceCallManager, and returns NULL for the origin's
|
||||
`emergency-numbers`, which is what
|
||||
`org.gnome.Calls.EmergencyCalls.GetEmergencyContacts` is built from. (The
|
||||
ModemManager provider does read it, via `mm_sim_dup_emergency_numbers()`.)
|
||||
An upstream fix would close this. Dialling an emergency number from the
|
||||
normal dialpad is unaffected — that reaches imsd's own classifier.
|
||||
- DTMF is forwarded to imsd, where `SendDtmf` is still a stub (RFC 4733 is not
|
||||
implemented yet) — the same limitation Plasma has.
|
||||
- **Restart GNOME Calls after restarting `imsd-ofonod` (or imsd).** When the
|
||||
modem's `VoiceCallManager` interface goes away and comes back, Calls 50.0
|
||||
adds a new origin but leaves the old origin's `CallAdded` handler connected:
|
||||
after one such cycle every call is added twice, after a few the stale handler
|
||||
runs on freed memory and Calls dies with SIGBUS in `g_hash_table_lookup`
|
||||
(measured on the FP6). Calls-side; an upstream fix belongs in
|
||||
`plugins/provider/ofono/calls-ofono-provider.c`.
|
||||
|
||||
Development, without a phone or root:
|
||||
|
||||
```sh
|
||||

imsd-ofonod — GNOME Calls backend for imsd (Phosh, GNOME Mobile).
|
||||
|
||||
Presents imsd as an oFono modem on the system bus: `org.ofono` with a Manager
|
||||
at `/`, one Modem + VoiceCallManager at `/imsd`, and one VoiceCall object per
|
||||
live call. GNOME Calls' bundled `ofono` provider plugin then drives imsd —
|
||||
dial, ring, answer, hang up, call history, contact lookup — with Calls, Phosh
|
||||
and GNOME Shell unmodified. It is the exact mirror of what imsd-dialerd does
|
||||
for Plasma Mobile's org.kde.telephony.*.
|
||||
|
||||
Why this seam and not org.gnome.Calls: that interface is what Calls *exports*
|
||||
so a shell can observe and control a call that already exists (Accept, Hangup,
|
||||
SendDtmf, Silence — there is no Dial, and no way to register as a call
|
||||
source). Phosh consumes it from Calls; nobody provides it to Calls. Calls'
|
||||
own backends are libpeas provider plugins (mm, ofono, sip, dummy) linked
|
||||
against private headers that no distro installs, so `org.ofono` is the only
|
||||
D-Bus seam a third party can implement.
|
||||
|
||||
Consumer-shaped details, verified against calls 50.0
|
||||
plugins/provider/ofono/ — get these wrong and the plugin silently ignores us:
|
||||
- the provider watches `org.ofono` on the SYSTEM bus and proxies `/` as
|
||||
org.ofono.Manager. A modem becomes a dialable Origin only while its
|
||||
`Interfaces` property contains "org.ofono.VoiceCallManager", so that list
|
||||
is our registration gate — the analogue of the dialerd's deviceUniList.
|
||||
- VoiceCall `State` strings are parsed as CallsCallState enum nicks:
|
||||
dialing / alerting / incoming / active / held / disconnected. imsd's
|
||||
"ringing" (a 180 from the far end) is oFono's "alerting".
|
||||
- inbound-ness is derived ONCE, from State == "incoming" as the call is
|
||||
added, so an MT call must be announced incoming and never corrected later.
|
||||
- DisconnectReason is cached by the plugin and read when CallRemoved
|
||||
arrives — emit it before the removal or the history entry loses its
|
||||
reason.
|
||||
- Dial's returned object path is ignored (the plugin waits for CallAdded).
|
||||
We return a real one anyway.
|
||||
|
||||
Runs as root because `org.ofono` is a system-bus name (policy in
|
||||
packaging/org.ofono.conf). It does no I/O beyond D-Bus: every call decision
|
||||
stays in imsd. Everything happens on the GLib main loop, so there is no
|
||||
locking.
|
||||
|
||||
--session own org.ofono on the session bus and talk to imsd there
|
||||
(development: no root, no policy file)
|
||||
IMSD_BUS=session|system override only the imsd side of that choice
