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

  • Fax over IP is on principle not supported by swisscom
    • The T.38 feature is not available
    • Fax via G.711 (T.38 to G.711 / Audio Fax support) is not supported by swisscom but should work in most scenarios. This Feature is not guaranteed!
  • Only G.711a is supported, no other codecs are supported
  • Overlapped Sending is not supported
  • NAT Detection is not supported
  • Redundancy Mechanism are not supported
  • SIP over TCP is not supported
  • Incoming Early Media Channel is not supported by default and must be requestet to swisscom.
  • CLIP no screening does not work for "Trunk loop Connections". This means, if you dial out to the PSTN and back to your own Trunk Number, CLNS does not work.


swisscom 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
  • Reverse Media Negotiation
  • Hold/Retrieve
  • Blind Transfer

Supported Codecs:

  • G.711a only
