No CID overwrite isn't active tried with and without, doesn't matter, .. this issue is been going on for a while.
I used to run elastix and there it always worked fine but for this trunk I wasn't able to set it right for some reason, not on ombutel nor on vitalpbx. I'm not sure why that is though.
I'm sure its some configuration, that needs to be done but can't put my finger on what it is.
*not sure but I believe it did work in one of the first releases of ombutel, .. have been using it since it released version 1 or something, I did make a post about it, but no one ever really to responded to it.
It's a betamax sip provider, .. the numbers have been verified, .. I can set them statically and if I would have one number it wouldn't matter, .. but that's not the case.
Is the Trunk configuration identical in both? I had similar issues when moving from Elastix to Ombutel. It turned out that there was a slight difference in the 2 trunks configuration. I can't remember what the issue was it was either the setting of from-user (which wasn't required) or the register string was slightly different.
I am pretty sure in my case my provider was sending on the From-User instead of the set caller ID. Unsetting From-user then used my caller id......
