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/C7
  - (20+ variants) MTP2, MTP3 and ISUP
- ISDN PRI
  - (14+ variants), National ISDN-2, Euro ISDN, DMS100, DMS250, 4ESS, 5ESS, Japan INS-NET1500
- CAS (Script-oriented approach):
  - CASR1:
    - E&M "Wink start" or "Delay start"
    - Loopstart (FXO and FXS sides)
  - CASR2:
    - generic(ITU base specification)
    - Brazil
    - Mexico

IP
- SIP RFC 3261 User Agent, SIP Authentication
- SIGTRAN
  - M2UA, M2PA and M3UA

TelcoBridges Tmedia devices also offer the conversion of signaling messages between nodes that use different signaling protocols
All supported protocols can be used simultaneously.
