Currently testing a DP-9841, the phone is able to connect to call manager (12.5-SU7) with no problem. When making outbound calls I don't hear a ringtone but the call is received, anyone has suggestions on where to start about the no ringtone when calling out ?

Is this issue occurring only with this specific phone model, or are other devices on your network affected as well? Also, could you let me know if your ISP connection type is SIP or ISDN?

Just on the 9841 model, which I am testing before deploying the phones out, we have a dedicated SIP circuit for testing. We have another production SIP circuit for which all current voice traffic is going out. I did some further testing, when connecting the 9841 to the production SIP circuit, I do hear the ringtone. I don't know if this issue might be at the SIP Router.

I found the root cause of the issue; we have an ACL that was causing the issue.
