I experienced this today. Doing a 'show channels' in Asterisk showed a Zap line perpetually ringing the sip phone even though the sip phone was reset a few times. Doing a 'soft hangup' on the stuck Zap and the Sip allowed 2-way audio to resume.

Hi Geoff,
You might want to try tcdump, specifying the source and destination IP (to minimize the info) and see where are the RTP packets going ; you will see if they change port or something like that
after a while.
Cheers,

    *Subject:* [Asterisk-Users] One Way Audio....in the middle of a call

    We had a user report that they were on a SIP <---> PSTN call for
    about 4.5 minutes before the call went to on-way audio. The user
    called the person back and they reported being able to hear my user,
    but my user couldn't hear them. The audio condition persisted for
    about 15 seconds before the user hung up.

    Where do I start to troubleshoot one way audio that occurs during a
    call?
