Signaling refers to the system of messages required to set up and tear down telephone calls between the calling and the called parties.
TelcoBridges and Signaling Protocols
TelcoBridges' products not only multiple signaling protocols but also provides mediation between different protocol vendors.
SBC
- IP
- SIP RFC 3261 User Agent, SIP Authentication
- Access to SIP headers
- Extensive SIP header manipulation
- SIP to SIP-I protocol conversion
- SIP registration forwarding, SIP subscribe/notify/publish forwarding
- NAT traversal
- SIP RFC 3261 User Agent, SIP Authentication
Tmedia
- PSTN
- SS7/C7
- ISDN PRI
- (14+ variants), National ISDN-2, Euro ISDN, DMS100, DMS250, 4ESS, 5ESS, Japan INS-NET1500, NET5 (France, Germany, UK, China, Hong Kong, Korea), NTT
- CAS (Script-oriented approach):
- CASR1:
- E&M "Wink start" or "Delay start"
- Loop start (network side and user side)
- ground start
- CASR2:
- Generic (ITU base specification)
- Brazil
- Mexico
- Venezuela
- CASR1:
- H.248
- GR-303
- The integration of the GR-303 protocol for Tmedia enables a seamless interoperability between GR-303 and H.248 as well as GR-303 and SIP.
- IP
Important Notes
- TelcoBridges Tmedia devices also offer the conversion (transcoding) of signaling messages between nodes that use different signaling protocols. For more information about Transcoding options, see TelcoBridges website.
- All supported protocols can be used simultaneously.
