As a single SmartSIP Trunk can support up to 1,000 channels, multiple Trunks become unnecessary. Unlike with ISDN, which typically supports 30 or 60 channels. Also, with Per Second Billing, you pay only for what you use and not a second more.
Traditionally, a large deployment, over hundreds of channels, would require multiple ISDN connections and PBX systems. With SmartSIP, you can scale up to 1,000 channels on a single SmartSIP Trunk,. This makes it easier to deploy and manage.
PSTN and ISDN services will be turned off in 2025. SmartSIP is the natural replacement without needing to completely replace your PBX equipments.
