I am configuring SIP and SCCP phone on CME Router. The issue is when i do conference for SIP phone calls are directly got dropped  for SIP phone but working for SCCP phones. Any suggestion to solve the issue. this behavior is only when calls are incoming and outgoing calls. for internal call conference are working for SIP and SCCP.

Please post your cme config. Also, did you enable conference hardware on voice register global? Did you configure dspfarms and included all codecs used in your environment?
