How to modify Listview of a subpanel?

Hi,

You can write process_record logic hook.

Which Sugar version do you use? Which edition?

You never should modify any core files, like files in the include/... directory, if possible.

Each such customization should be done in the custom/... directory to creatze upgrade safe customizations.

The phone numbers are stored in phone fields, so if you look in the definition of these phone fields (e.g. in include/SugarFields/Fields/ (6.x) or clients/base/fields/ (7.x)) you are at the right placeto start with some customizations.
On the other side there is a so called "SkypeOut®-Integration" option which can be set in admin - system settings which creates a callto:-reference on phone numbers (which is accepted by some other cti integrations too). This feature creates a callto:-reference every time a phone number starts with + or 00 or 011.

Sugar Version 6.5.23 (Build 1061) 

Can I access subpanel data (in detail view) using logic_hooks.
