First of all, you will not get a user's phone number from the Glip Person API as phone number is not required by Team Messaging.

There are 2 kind of user types in a chat, a team or a conversation, internal user or external user. You can read the phone number(s) of an internal user using the API chain below:

1. Read your account info to get the account id (if you don't know it)

2. Read the team/chat/conversation and parse the members array to get their id

3. Read the user profile of each member using the member id

4. Compare the account id (read from step 1) with the 'companyId' in the response from step 3. If the Ids match, it is an internal user => Read the user phone number. Else => ignore external user

5. Read extension phone numbers

Hope this helps!

Hi @Phong Vu , thanks for the quick response.

Is there any way to get phoneNumbers of person not from my company?

For example,

I'm contact A from company A and I have a team with member -> contact B from company B.

From team members I know only id of contact B, using https://developers.ringcentral.com/api-reference/Profile/readGlipPerson with id I can get some information about contact B, but there is no extension and phoneNumbers.

I want to call him, is there a way how I can get his phoneNumbers using API?
