[Ticket Question] Help with an old Videx entry system please

[securitywarehouse]

We are electrical contractors,we have a site that contains an existing videx entry system(looks approx 5 10 years old)we've been asked to add an additional audio entry phone. can we simply cable from the existing handset to a new one? We think the intercom phone serial no is VX Smart LC631/03
