The problem is that for analizing the call I need only 1 pcap file with all the packets in the call, but what I have is 2 differents pcap files (one from each mobile phone). My question is if it is possible to mix the 2 captures in only one file. Then I would have all the traffic within the call in the same capture and I will be able to analyse it as a complete VoIP call.

That's exacly what the tool "mergecap" can do for you. Mergecap is 
distributed with Wireshark. You can also load one tracefile in Wireshark
and select File -> Merge from the menu to merge it with the second file.

Hope this helps,
Cheers,
