  • DTMF

• Supported Codecs by the provider
  • G711
  • G729
  • GSM
  • T.38 UDP

The Reverse Media Negotiation is not supported, therefore Media Relay/RTP Proxy must be activated, in order to preventmedia negotiation problems while transfer the calls.

T.38 is stated as supported, but no Fax transfer was possible, due T.38 negotiation problems. The T.38 gateway on provider site exceeds T4 timer of the T.30 protocol. The issue is under review on the provider site.

Configuration

Firmware version

All innovaphone devices use V8 hotfix2 build 80500.04 as firmware.

SIP-Trunk

The SIP interface must be configured to act always as media relay, since no reverse media negotiation is supported. Also codec as exclusive must be activated in order no renegotiation can happen.

The From Header and Identity Header must be configured to send CGPN in user part of URI and Fixed AOR, in order the DDI works correctly.
