Hi. Thanks for answer.

Now call transfer work follows:

Cisco SCCP ipphone - Cisco SIP ipphone - Avaya ipphone - success

Cisco SIP ipphone - Cisco SCCP ipphone - Avaya ipphone - unsuccess

Avaya ipphone - Cisco SCCP ipphone - Avaya ipphone - success

Avaya ipphone - Cisco SIP ipphone - Avaya ipphone - unsuccess

Call Transfer CME-Avaya

Add these and then check.

voice service voip 

 sip

  bind control source-interface xxxxxx
  bind media source-interface xxxxxxx

Thanks
