SIP Configuration

This page describes the requirements to connect to Omilia Cloud Platform (OCP®) using SIP, such FQDNs, allowlists and codecs.

SIP URI

To establish a connection with the Omilia Cloud Platform, direct your communications infrastructure to the appropriate localized region-specific SIP Domain URIs.

SIP Domain URI

Region

us1-s.ocp.ai

US

eu1.sip.ocp.ai

EU

The SIP Domain URI corresponds to several SRV records. All nodes support UDP, TCP and TLS. For the purpose of connecting to OCP, it is advised to use the Fully Qualified Domain Name (FQDN), rather than the IP addresses listed below.

Media Codec & Companding

Media codecs supported:

  • PCMU / G.711 μ-law

  • PCMA / G.711 A-law

DTMF

DTMF Method supported:

  • Inband

  • RFC2833

Encryption

OCP® supports encryption of SIP calls with SIP over TLS (SIPS) and encrypted RTP (SRTP).

SIPS

For SIPS, OCP® requires TLS 1.2 or later.

Certificate Authority

We use the DigiCert Certificate Authority (CA) to sign our certificates. Your equipment must support root and intermediate certificates from this CA to enable SIPS on OCP®.

SRTP & SRTCP

OCP® supports media encryption using SRTP and SRTCP with AES as the cipher.

IP Addresses 

Please ensure that your firewall settings permit all SIP and media endpoints for your preferred region.

OCP SIP & Media endpoints are scalable. This means that not all below mentioned IP addresses are permanently live. Endpoints are enabled as required.
