Plivo: ₹250/month rental, ₹0.74/min incoming, ₹0.40/min outgoing, billed per full minute (plivo.com/voice/pricing/in). Vobiz: $5/month when bought inside Bolna (about $1/month direct from Vobiz), $0.0055/min incoming and $0.0115/min outgoing, from Capterra listings that may be out of date. Confirm both with the provider.
Voice & AI
The speech and Bolna rates are rough placeholders, so check sarvam.ai and bolna.ai for current prices. The AI cost is worked out from token prices, assuming about 4 replies per minute. Each reply resends about 3,000 tokens of instructions and history, mostly cached, and produces about 150 tokens of speech and reasoning.

Ways to save
Send WhatsApp or SMS reminders first, and call only the customers who don't reply. This cuts outgoing minutes.
Forward your existing shop number to the AI number only when you're busy or don't answer.
Try a lower-cost model in the simulator first. Switch only if the Telugu quality is still good.
Keep replies short. The prompt already asks for one or two sentences.
