Hello Linphone / Belledonne Communications team,

I=E2=80=99m planning to run my own SIP infrastructure (Flexisip) and would =
like to
support reliable push notifications on iOS/Android while continuing to use
the official Linphone mobile apps.

Could you please advise whether you offer a paid SaaS / service that
enables push notifications for third-party SIP accounts (i.e., accounts
registered to our own Flexisip server) on the official Linphone iOS/Android
apps?

In particular, I would appreciate clarification on:

1) Availability / Scope
- Do you provide a push notification SaaS that works with the official
Linphone iOS/Android apps for third-party SIP accounts (our own Flexisip)?

2) Service architecture
- If available, which model applies?
(a) Belledonne operates a hosted =E2=80=9Cpush service=E2=80=9D that relays=
 notifications
for our users, or
(b) We configure our Flexisip to connect to your service / gateway, or
another integration approach
- Any required configuration details or prerequisites would be helpful
(high-level is fine).

3) Commercial terms
- Pricing model (per user, per device, per MAU, etc.)
- Minimum number of users / minimum monthly commitment
- SLA / support scope and response times

4) Technical requirements
- Required server components and minimum specs (we currently plan to use a
small VPS initially)
- Required ports / TLS requirements, certificates, etc.
- Supported client versions (Linphone iOS/Android: which versions are
supported, and any limitations)

5) If the above is not possible
- If push notifications for third-party SIP accounts on the official
Linphone apps are not supported via SaaS, could you provide an estimate for
a white-label / branded mobile app (iOS/Android) including ongoing
maintenance/support?

If you need more context about our use case or architecture, I=E2=80=99m ha=
ppy to
share details.

Thank you in advance, and I look forward to your guidance.

Best regards,
Daisuke Ushijima
