CCM6: IPC (SCCP) fails to call 3rd party SIP

Hi

I have IP Communicator 2 registered to CCM 6.0 with SCCP (DN 1007 on pcap) and 3rd party "P2000W" registered with SIP (DN 1009).

I'm able to place calls from the SIP to SCCP but when trying opposite IPCC gets a busy tone. Wireshark sees SIP msg 400, pcap attached.

CCM or codec problem, don't get it? CCM has very basic setup and auto registering. Any tips appreciated.

Wbr, tonic

3rd Party SIP Phones are not supported as contact center agent phones. The SIP protocol standard does not include the necessary messaging for 3rd Party Call Control (3PCC). Cisco Unified Contact Center Enterprise relies on CTI capabilities on the SIP phones which 3rd party phones do not have. As an alternative, you may choose to deploy the Mobile Agent solution to enable Cisco Unified CCE and CCH to use any phone as an agent phone.
