No ringback in a QSIG connection to an Ericsson MD-110 PBX

I have a E1 controller in a 3745 gateway connected to a MD-110 PBX, configured with QSIG signaling. We are using CCM 3.3.2. The problem is that I am not receiving the ringback in the IP phones (no problem in the phones connected to MD-110). When you configured the endpoint with PRI Protocol Type “PRI ISO QSIG E1”, all the fields in PRI Protocol Type Specific Information are greyed and you can not make any selection (like checking “Setup non-ISDN Progress Indicator IE Enable”).

We had to solve this with

voice call send-alert on the router-config.

maybe this will help.
