Replaying SIP calls, showing Out of Seq:1(100%)

0

I'm trying to capture and replay VOIP conversations on my local network using Wireshark. I've tried multiple audio codecs and softphones but I'm unable to replay the audio using Telephony -> VOIP Calls -> Player -> Decode. Wireshark detects the VOIP call and shows the correct duration but every decode results in showing "Out of seq:1(100%)" and "Duration:0:00" in the RTP player. The traffic is not being encrypted and the sequence numbers in Wireshark seem to be fine. Any ideas?

Update: I resolved this issue by setting up my own SIP server using FreePBX. I assume that this problem was somehow related to NAT-ing the traffic from my internal network to the SIP provider and then back to my other softphone on the internal network.
