Checking that Audio is Transmitted to the Correct Remote Address

Use pjsua's dq (dump quality) command to see the address where RTP packets are transmitted to:

>>> dq
 19:01:38.878        pjsua.c
  [CONFIRMED ] To: sip:localhost;tag=213e15bcf98b4c0394a402881e885431
    Call time: 00h:01m:44s, 1st res in 1452 ms, conn in 1682ms
    #0 iLBC @8KHz, sendrecv, peer=192.168.0.66:4000
       RX pt=117, stat last update: 00h:00m:01.943s ago
          total 4.3Kpkt 164.0KB (302.2KB +IP hdr) @avg=12.5Kbps
          pkt loss=0 (0.0%), dup=0 (0.0%), reorder=0 (0.0%)
                (msec)    min     avg     max     last
          loss period:   0.000   0.000   0.000   0.000
          jitter     :   0.125  15.779 1695.000   1.250
       TX pt=117, ptime=20ms, stat last update: 00h:00m:09.304s ago
          total 5.1Kpkt 197.2KB (363.4KB +IP hdr) @avg 15.0Kbps
          pkt loss=0 (0.0%), dup=0 (0.0%), reorder=0 (0.0%)
                (msec)    min     avg     max     last
          loss period:   0.000   0.000   0.000   0.000
          jitter     :  14.750  15.570  18.875  18.875
      RTT msec       :   0.854  24.516 125.000  18.783

The important bit of above output is this line:

    #0 iLBC @8KHz, sendrecv, peer=192.168.0.66:4000

which tells us that RTP packet is transmitted to IP address 192.168.0.66 and to port 4000.

Verify that this is indeed the correct address where remote is expecting incoming RTP packets.
