FAQs
Common questions
Still curious? Reach out and we’ll walk you through it.
Does RCS work on both Android and iPhone?
Yes. Summit ships RCS clients for Android, iOS, iPadOS, macOS, Windows, Linux, web, wearables and immersive devices, so every screen stays in sync.
What standards does Summit’s RCS support?
The RCS Universal Profile for messaging, IR.92/VoLTE for voice, IR.94/H.264 for video, and EVS, AMR-WB and OPUS for audio.
Can we integrate just part of the platform?
Yes. Summit offers three levels of RCS APIs (high-level, intermediate and fine-grained) so you can add communication to an existing app or build an entirely new service.
How is RCS different from SMS or MMS?
RCS adds rich cards, suggested actions, group chat, read receipts and a unified RCS/SMS/MMS inbox on top of the messaging your customers already use.
Do you support carrier-grade IMS deployments?
Yes. Presence and capability discovery run over SIP OPTIONS, and interoperability is verified against leading IMS cores, SBCs and application servers.
How do we get started?
Start a conversation with the Summit team and we’ll scope a pilot around your network and goals.
