Hard to help you without getting proper details.
Provide Asterisk CLI output when call gets disconnected.

You are using an obsolete version of Asterisk (and not even the latest subversion of that). You also haven’t provided any debugging information.

There is no standard dialplan with Asterisk, so I have no idea what precedes your call to Background.

The most common causes of dropped connections in Asterisk 1.6 (broken peer re-invite implementations) only applies after the call has been connected through.

I believe directrtpsetup is buggy in that verion, but should only apply to the outgoing side.

Hi All,

    Please find the sip debugging output as below.

The call has been cleared by the other party, as a normal call clearing.

Hi,

  We're unable hear the audio for sip incoming calls.

Regards,
Radha Krishnan

david55 · November 15, 2013, 12:48pm

One way audio is normally due to NAT or firewall misconfiguration.

In your case, you seem to be using 10.x.x.x addresses for everything, but the remote media address is considerably different from the remote SIP address, so I suspect that there is routablity between the SIP subsystem and Asterisk, but not between the actual media source and Asterisk.

You are getting SIP from :10.140.0.2 but the remote media end point is 10.140.1.154.
