Door Entry Handset Replacement wiring problem

[Taylor_b_c]

I have replaced my old door intercom handset. I live in a block of flats which use phones with buttons to open the main door or visitors. The old handset is a Comelit Vox 2000 and I have bought a replacement Urmet 1133/15. I have attached a list of comparable wiring diagrams given by Urmet. The problem is that visitors can not hear my voice when I use the handset. I can hear the visitors and the buzzer also works fine when opening the door. I have also tried to adjust the mic and speaker dials on the new system without any resolution.

I have attached a few pics of the old intercom and a few pics of the new so you can see the wiring. Would appreciate any suggestions as to solve this. Many thanks.

Did it work before ?
Why didn’t you purchase a comelit handset ?

the Comelit Vox 2000 was an old and existing installation that used to work. It recently had noisy (noise from the speaker i the handset). there is also a red button on the handset you have to press in order to speak. In the Urmet 1133/15 there is not a a similar button when you have to speak.
