Trouble getting a SIP Device about atapi.net

[rum80]

Hello Randeep,
I am quite sure that issue is not related to ATAPI at all, but due to a CUCM misconfiguration.

To be sure: just open a TAPI client, such as phone.exe, see here, and look whether those SIP lines are present or not.

If, as I think, SIP lines are not present, I suggest to check permission of the CUCM Application User you're using. In particular, ensure user has privileges:

• Standard CTI Allow Control of Phones supporting Connected Xfer and conf
• Standard CTI Allow Control of Phones supporting Rollover Mode

BTW, the right place to investigate Cisco CTI issue is this forum.

Regards, Marco.

Hello Marco,

Indeed you are right and thank you for posting the answer so quickly. After further reading and exploring, I discovered that 3rd Party SIP Devices do not have this flag to turn on for calling monitoring:
"Allow Control of Device from CTI".

So, even after setting the permissions as you stated in your email I couldn't get access to the phones (even using phone.exe).

Thank you for the resources provided, I will close this issue now as it needs to be answered by Cisco really.
