Sorry , I forgot to say that some packets coming from Twinkle are SIP & ARP packets not only RTP.Hence , I think I need to receive RAW packets in GNU Radio ( as I have different type of packets: RTP , ARP , SIP packets)
Note that :I use 4 laps & 2 USRPs.1st & 4th lap has twinkle softphone & I will make a call between them.2nd lap has an OFDM TX implemented by Gnuradio.
3rd lap has an OFDM RX implemented by Gnuradio.First and 2nd laps are connected by Ethernet cable.3rd & 4th laps are connected by Ethernet cable.One USRP is connected to the 2nd lap , the other USRP is connected to the 3rd lap.
2nd lap(GNUradio ,ofdm tx) will receive the packets from 1st lap(Twinkle) using RAW socket (as I think ) .2nd lap will send the packets to the 3rd lap by the USRPs.3rd lap ( Gnuradio , ofdm rx) will send real time voice packets to 4th lap (Twinkle) using RAW socket(as I think).
