      <p>Dear,<br>
      </p>
      <p>Kindly guide with the 2 issues mentioned below<br>
      </p>
      <p><b>#1</b> - <b>Host unreachable 0 last qualify 0 (only in 3G</b><b>)</b><br>
      </p>
      <p>I am trying to use SIP client over 3G. It registers and call
        can be initiated from the client but it can't receive call;
        cause <b>asterisk sever </b>marks it as unreachable
        immediately after registration.</p>
      <p> </p>
      <p>"[2014-10-08 14:32:47] NOTICE[1610]: chan_sip.c:29596
        sip_poke_noanswer: Peer '1007' is now UNREACHABLE! Last qualify:
        0"<br>
      </p>
      <p>The above work well when I turn off 3g and switch over to my
        office wifi. Kindly guide if there are specific settings for 3G
        / mobile network.<br>
      </p>
      <p><b>#2</b> - <b>SIP retransmits - no reply to our critical
          packet</b><br>
      </p>
      <p>Issue occurs when dialing a call out from a remote wifi network
        ( in my case office wifi ), Its auto disconnected within 10s
        with SIP Retransmissions notice / warning message<br>
      </p>
      <p>However if a call is initiated from home local network ( ipad )
        to the phone ( registered with asterisk over office wifi )...
        all works well !<br>
