Cloud PBX to On-premises PSTN via SfB CCE
Hi Michael,
If I understand this correct, You are having Problems with Outbound Dialing with CCE, Meaning SFB online User makes an outbound call to PSTN. In This case the Signalling would ideally work this way
Online User CLient Sends Invite with a To header which will have the Telephone number called in the format To: <sip:+1XXXXXXXXXX@Domain.com;user=phone>, This Invite goes from CLient to Online FE/Director --> Online Edge --> CCE Edge --> CCE mediation --> PSTN gateway
So the To Header that you are seeing should ideally be the same throughout, What logs did you find the To header in the IP format? might be good to check the client log as well for the Outbound Invite to see what is the TO header there and then the incoming Invite into the CCE edge to see what is the To header in that, which should then be carried over to mediation.

Mohammed, your understanding is correct, and thank you for taking the time. The situation was my fault. A configuration error in my firewall was causing the issue. Thanks for your response, it set me on the right path.
