VeriSign® ISUP Trunk Signaling - Signaling from VeriSign, Inc.

VeriSign® ISUP Trunk Signaling



Virtually Instant Connections Help Save Time and Money

VeriSign® ISUP Trunk Signaling replaces slow in-band signaling with out-of-band data links using the ISUP layer of the SS7 protocol. By removing signaling traffic from voice trunks, carriers have more capacity in existing networks without network build out. Customers experience virtually instant connections and have access to Intelligent Network services.

Increase Network Efficiency

With the largest independent SS7 network in the Americas, VeriSign has comprehensive connectivity arrangements and direct access to LATAs. Carriers can depend on cost-effective routing and call set-up with VeriSign as the single interconnection vendor.

Increase Revenue by offering Advanced Services

ISUP Trunk Signaling enables easy deployment of the services callers demand: caller name, caller ID, E9-1-1, and more.
