Dinstar MTG200 1*E1 T1 PRI Trunk Gateway with G.723/G.729/ILBC Codec
The Dinstar MTG200 is PRI to SIP trunking gateway. Very good choice for budget conscious people. It is certified to work with Asterisk, Freeswitch and its derivatives.
Description:
- 1 E1/T1 port (configurable as either E1 or T1).
- Supports PRI (Primary Rate Interface) signaling.
- Converts TDM (Time Division Multiplexing) voice from E1/T1 to SIP VoIP.
- Acts as a gateway between legacy PBX systems and modern IP-PBX systems (like Asterisk, FreePBX, 3CX, etc.).
- Usually includes echo cancellation, fax support (T.38), TLS/SRTP, and multi-language IVR.
- G.723.1 Codec Support – Offers high compression (5.3 & 6.3 kbps), suitable for low-bandwidth VoIP calls.
- G.729 Codec Support – Widely used for IP telephony with 8 kbps bitrate, providing clear voice with minimal data usage.
- iLBC (internet Low Bitrate Codec) – Excellent for unreliable networks; resists packet loss and jitter.
- Bandwidth Efficiency – All supported codecs are optimized for low bandwidth while preserving voice quality.
- Adaptive Jitter Buffer – Improves quality when using codecs like G.729 or iLBC over unstable networks.
- Silence Suppression (VAD) – Reduces bandwidth usage by not transmitting silence during calls.
