called name between avaya I P office & CUCM via SIP trunk

[DiyFrea]

When dial extension from IPO users to cisco cucm users via SIP, IPO users can see called number and name for cisco users on avaya phones but
When dial extension from CUCM users to IPO users, Cisco users see called number without name for IPO users on cisco phones

Is this problem from IPO or CUCM

P-Asserted-Identity & remote-party-id show the extn name in CUCM Instead of the remote extn name in IPO for calls that dial from CUCM to IPO
