  • [x] I verified that the Quickstart application works in my environment.
  • [x] I am not sharing any Personally Identifiable Information (PII) or sensitive account information (API keys, credentials, etc.) when reporting this issue.

Code to reproduce the issue:

call.sendDigits('wwwwwwwwwwwwwwwwwwww123');

Expected behavior:

A pause of 10s (500ms per w) then the tones for 123 are played on both caller and callee's end.

Actual behavior:

On the caller side, a pause of ~5s occurs then tones for 123 are played. On the person who is getting called, they hear the correct 10s pause then 123.

Software versions:

• [x] Browser(s): Chrome v125
• [x] Operating System: MacOS 14, Windows 10 & 11
