As a single SmartSIP Trunk can support up to 1,000 channels, multiple Trunks are not unnecessary. This is unlike ISDN, which typically supports 30 or 60 channels. Also, with per second billing, you pay only for what you use, 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 deployment and management easier.
PSTN and ISDN services will be turned off in 2025. SmartSIP is the natural replacement without the need to replace your PBX equipments completely.
Future-proof your communication systems by moving to a SIP Trunk based telephony solution, the foundation of modern unified communications solutions for businesses.
