Signaling refers to the system of messages required to set up and tear down telephone calls between the calling and the called parties.

TelcoBridges provides support for the following signaling protocols:

PSTN
- SS7
  - (20+ variants) MTP2, MTP3, SS7/C7 TCAP and ISUP
- ISDN PRI
  - (14+ variants), National ISDN-2, Euro ISDN, DMS100, DMS250, 4ESS, 5ESS, Japan INS-NET1500
- CAS (multiple variants):
  - MF-R1, MFC-R2, Loop Start, Ground Start, Wink Start, Robbed-bit signaling

IP
- SIP RFC 3261 User Agent, SIP Authentication
- SIGTRAN (currently in development; targeted for end of 2009)

Important Notes

TelcoBridges Tmedia and Tdev devices also offer the conversion of signaling messages between nodes that use different signaling protocols. All supported protocols can be used simultaneously.
H.323 is not currently supported
