We are using netborder express (a200 analog) on snom one plus. We can't get caller id information on incoming calls. We have FCT analog cellular gateways connected to sangoma ports. I already tried to connect analog phone to fct directly, and i can see caller id on the analog phone. Also when we connect these FCTs to another systems like Alcatel-Lucent OmniPCX Office, caller id is working fine. You can find the information about FCT in the link below.
Log file i got from sangoma is in the attachment. I already talked with sangoma support and they said that i have to talk with provider :/
Can you please help us in this case?
