Is it possible to support Phone Numbers?

[robi]

find the log? is it a permissions issue?

or an entry format issue?

This is something you have to configure in the homeserver config file. 3pid (third party ids) in matrix can be email and MSISDN (phone numbers).

From what I can tell, you have to first setup a msisdn delegate and also set disable_msisdn_registration to false i guess.

I haven't found any docs on how what this msisdn delegate is though.
