I haven't played in awhile but can't you just click on the phone notification and chat with him? Might be the solution

i had the same problem. i started the game over and made sure not to go into the phone while skipping and i was able to get through.

Sorry, only just saw this. This is fixed in the next version which isn't released yet, but in the meantime you can progress past this using the console. Google the steps to enable the console in Ren'py, then once you've done the steps, load your save and progress to part with through that text conversation. Then open the console with Shift+O, and type the below exactly as written (Case sensitive)

messageCount = 1

Then press enter. It should then let you keep playing beyond the end of that text conversation.
