I was wondering if it is possible and if it makes sense to create a subform for contacts which consists of labels and phone fields. The reason is, we have ofter customers with a big variety of phone numbers and I dont want to create 10 more "other phone" fields, especially as we would need individual labels.

Question now: are there any downsides of working with a subform? if i integrate later on with my phone system /PBX, which fields are used to lookup for contact information? Does Zoho CRM use any phone field somewhere in the system or just any phone field directly in contacts and accounts?

many thanks
