Okay, looked at the pcap and see the fragmentation, but that does not indicate your asterisk IP stack is not handling it properly. Might compare a 'sip debug' with those packets to see if data is reassembled. Since both pieces of the original fragmented packet did in fact arrive at your destination, the only issue left is whether your IP stack reassembled them properly. I'd suspect another problem is lurking unrelated to fragmentation.
