Talkdesk stores every interaction a contact has with your company, in the corresponding "Activity" tab.
Here, you can see all inbound and outbound calls, voicemails, chat transcripts, tickets, cases, notes, etc.
Talkdesk also pulls information from all your other integrated business tools (i.e. Salesforce, Zendesk, Olark, ZoHo, Highrise, Desk.com, etc.) and puts this information in the contact's "Activity" tab.
To open a contact's Activity list, simply click on the contact's name or phone number in the following places:
- "Calls" section  (previously, "Call History").
- "Voicemails" section.
- "Contacts" section.
- Keypad, when a call is ringing or while on a call.
- Any other link where it may be showing.
Select the contact's 'Activity' tab .
If you wish to check all notes left during a call with this contact, click the '+' button  next to the corresponding entry. To listen to the call or voicemail click the “play” button :
Interactions displayed from an external system can have several options associated:
