[Asterisk-Users] Bad Checksum answering inbound call

[pdhales at optusnet.com.au]

OK - what does the screen on the Asterisk box say? 

Off hand, it sounds like a codec issue. 
But the fact that your service provider says that you are not providing an answer signal points more to a dialplan.
(ie: Adding an 'answer' to the dialplan)

  The server is hosted in Soul's data center and the connection is using SIP to a VEP directly on their voip backbone.

   

  We have tried putting a Sip phone directly on to the connection and it works fine.

   

  Thanks

    Could anybody please help me with problem.. 

     

    Outbound calls work fine, however inbound calls ring the phone, then answering the call, the service provider doesn't receive the "picked up" message from asterisk.

     

    We have narrowed it down to an incorrect checksum in the packets being sent back from asterisk after answering an inbound call.
