Call Park with CUCM - need Cisco license to develop?

Hi,

I'm looking to understand what it takes to support call park from a phone with CUCM.

Do you still need to obtain a license from Cisco to interface into the extended SIP line interface?

Still need to be a CTDP member and have a developer service contract?

Any up to date documentation on this? All I've found is old stuff listed below.

Overview: Cisco Unified CallManager 5.0 Session Initiation Protocol (SIP) Line Extensions

https://developer.cisco.com/site/uc-manager-sip/documents/sip_line/

That indicates we require a license to obtain this relevant documentation.  Here is an exert from the above doc:

The extended SIP line interface for Cisco Unified CallManager 5.0 provides proprietary extensions to the SIP standards. These extensions are briefly described here to provide an overview of this added functionality.

Note:  The extended SIP line interface contains Cisco's intellectual property. Any party wishing to incorporate any functionality in its products in accordance with the extended SIP line interface must obtain a license from Cisco.

Licensees for the extended SIP line interface must first be members of the Cisco Technology Developer Program (CTDP) and must have a Cisco Developer Services contract. You can find information on how to become a member of the Cisco Technology Developer Program or how to obtain a Developer Services contract at http://www.cisco.com/go/ctdp. Finally, if you would like to contact Cisco directly, please send all inquiries to: ipcbu-busdev@cisco.com.

However I cannot see this document on the following page: http://developer.cisco.com/web/sip/docs

In particular I'm looking to do Call/Park pickup via the extended SIP line interface from a SIP phone with CUCM.

Thanks, SImon

Hi Simon,

Yes you do need to sign a TLA with DevNet to obtain the latest SIPE documents and engage in the QED process to develop this feature for your SIP endpoint.
