Not determined the phone number in FXO gateway-grandstream UCM, which caller id scheme to choose?

The operators who save are not determined by the numbers that arrive at the copper port analog gateway grandstream ucm 6204.

That is:
1. ONT hg8245q
2. grandsteam ucm6204
Wiring diagram ONT->FXO1 ucm. Ie ONT instituted the sip account tied to the FXS port of the ONT, then ordinary copper in the FXO port of the UCM on UCM analog trunk.
Wiring diagram raises a smile, but it is necessary, the provider refuses to give up on the normal sip trunk, nails nailed it to the ONT and left in nesoznanku.

Because one line is enough, in principle, are satisfied with the solution, the calls come and go, problems with sound no, at least he's converted from digital data to analog then back to digital.
And all is good, but the phone numbers of incoming calls are not detected at all.
I'm not a real welder, telephone operator, poorly understand the mechanism of the caller ID, but something tells me that you should open the settings of the analog trunk to select the correct caller id scheme. And the choice was large enough, configured it all remotely and brute force to choose the right is not an option.
I waste avtodetekt and ETSI-DTMF and CDR logs I see Undetected 0000 [Trunk: LandLine] or Anonymous [Trunk: LandLine] and I was somewhat sad.

Actually questions:
1. And should work the determinant in such a spike in the connection diagram?
2. Maybe you have to press what button in ONT? While there is no access and it is not clear whether to climb.
3. What to smoke on this subject, to full enlightenment?

If you connect the phone instead of ucm the number on it determined?
That's a good clarification to my question, as I myself didn't think about it. Ask remote hands to check if there is a tube with a determinant. - Chanc commented on March 19th 20 at 08:55
Tucked the phone - number is not defined. In the face ONT room glows. Well, we think that the ONT does not transmit the number of the incoming call. Behind this question can be closed. - Chanc commented on March 19th 20 at 08:58
