Description (partial)

Here SCCP phone is registered to publisher and using MTP(passthrough) registered to Subscriber. In other end SIP Phone is registered to other callmanager. There is a SIP EO trunk between both the callmanager.

This issue is seen only when 8961 sip phone  is used. 
 Here both the end points are having video caps  but the negotiated capability is audio. 
  As both the end points are  having video caps, The video m-line becomes  true, hence   videoSdpModeToPeer become SendOnly, which leads to sending a  reoffer.
