There's no SIP involved until the call is picked up -- only PSTN and
IAX2. No RTP log available either.

After looking further, the problem seems to be purely in playing
recorded messages over IAX2. Looking at the debug logs on the SIP
server (which is playing the recorded messages) shows that it stops
playing one of the messages at some point in the flow, and then never
plays anything again.
Here's the logs from three different calls:

All this works perfectly when tested from a client logged in to the SIP
server itself. The problem only arises when a caller calls the Dial
server from the PSTN, which then passes the call to the SIP server over
IAX2.
