Nooks vs Trellus
What works
Trellus lets a caller start with one paid seat and work from a supported platform. The parallel plan supports up to five lines and includes extra phone numbers with spam remediation.
The drawback
Trellus labels its calling limits as standard or high. Ask for the exact allowance and extra-usage rates on your order. There is an interactive tour, but no free calling trial.
Cost and add-ons
Power is $99.99 per seat monthly. Power + Parallel is $149.99. Business pricing is quoted. Calling credits can depend on duration, destination and connected call legs, including voicemail, under eligible credit-based terms.
