- ISDN gateway During connection establishment, the ISDN terminal devices negotiate which codecs are to be used to compress the voice data. Use the codec filter to restrict the codecs that are permitted and to permit only certain codecs.
- Analog gateway Use the codec filter to restrict the codecs that are permitted for analog terminal equipment and to permit only certain codecs.
- DTMF signaling
- SIP info: Transmits the DTMF tones according to the SIP info standard
- Events (RFC 2833): Transmits the events in cleartext according to the RFC 2833 standard
- Tones (RFC 2833): Transmits the tones according to the RFC 2833 standard
- Events&tones (RFC 2833): Transmits the events in cleartext and tones according to the RFC 2833 standard
Note: The DTMF signaling settings must match the SIP provider requirements. Defective DTMF signaling settings could make it impossible to establish a connection via the SIP provider.
