Not enough information. There can be a bug in the VoIP call parser, there can be some kind of non-symmetric codec use where both phones can play the streams but Wireshark cannot play one of them, there can be some issue with the capture.... hard to say without seeing the actual capture, but you may have some privacy issues so you have to choose a call which you know not to have any important information in it.

If its not wireshark supported codec to be played out, then you have to do some packet shaping... Basically determine the codec following the SIP/SDP, export payload, remove headers, re-formulate the payload and feed it to the proper reference decoder.
