What's harder: Building the AI brain or connecting it to telephony?

Genuine question for the community.

With APIs like OpenAI and Claude, building conversational intelligence has become significantly easier. But when it comes to production voice applications, the telephony layer often becomes the bottleneck.

Things like:

  • Handling call state and interruptions

  • Managing latency for real-time conversation

  • Supporting Indian languages (Hindi, Tamil, Telugu, etc.)

  • Dealing with poor network conditions

Where do you spend most of your debugging time?
