Please Note, that some features are restricted or not supported by Sunrise

  • The T.38 feature is not available
  • Fax via G.711 (T.38 to G.711 / Audio Fax support) is supported by Sunrise and work in most scenarios.
  • Only G.711a, G.711u is supported, in special cases G.729 is supported, no other codecs are supported
  • Overlapped Sending is not supported
  • NAT Detection is not supported
  • Redundancy Mechanism are supported when using two Sunrise Gateways
  • SIP over TCP and SIP over TLS is not supported
  • Call using SRTP are not supported

Sunrise doesn't support "Reverse Media negotiation". Because of this, "Media-Relay" and an "Exclusive Coder Setting" must be configured. In contrast to a SIP trunk which does not need Media-Relay, the transport of all RTP packets across the gateway will result in a higher CPU load.

In order to use some Features like Clip no screening, some configuration must be done.

Supported Features:

  • Direct Dial In
  • DTMF
  • CGPN can be suppressed
  • CLIP No Screening
  • Hold/Retrieve
  • Blind Transfer

Supported Codecs:

  • G.711a, G.711u and in special cases G.729 only
