Userspace VoLTE/IMS daemon for mainline Linux phones (developed on the Fairphone 6): a GLib-free core (SIP, SDP, USIM AKA, IPsec SA setup, RTP media, call engine) behind a GDBus control daemon, a standalone AMR-WB media leg, and a Plasma Dialer backend. C++26 modules built with Crafter Build; the tree is clean under the project's house-style linter (crafter-build lint) across all three build products.

Description=Userspace IMS/VoLTE daemon (SIP register + calls over the ims PDN)
|
|
# needs the ims PDN (multiplexed netdev + global v6) — ims-pdn-up.sh
|

# creates/connects the bearer through ModemManager and configures the netdev
|

After=ModemManager.service network.target

Type=simple

# bring up the ims PDN first; waits for modem + LTE attach, idempotent.

# worst case ~4 min (modem wait + connect retries), hence TimeoutStartSec

# /etc/imsd.env: admin configuration — PCSCF= is REQUIRED (the carrier's

# P-CSCF address; see the README's Configuration section) and wins over the
