Hello, I have been looking in this forum and in other webs but I haven't found any solution. The problem is that when I create an extension in Elastix and connect in that extension an other PBX in which I have that extension configurated as a trunk, although I configure in the second PBX each extension with a different CID or even if I force in that trunk a CID, it never overwrites the CID I put in the second PBX to Elastix extension number. If I put in Elastix the CID it works ok, but if I leave it blank it sends as CID the extension number intead of the second PBX. What I need is that each extension of the second PBX overwrites the Elastix extension's CID. How can I do it? Thank you.
