Badalian Vyacheslav commented on ASTERISK-25715:
------------------------------------------------

Gerrit dont support add patch with Web UI (i dnot found in docs or UI). Servers in Datacenter does not have access to external network. I can't do {{git review}}. I have only ssh access to this servers. 

In most cases they are in draft status and show the place and the idea of a fix. But I'm not so familiar with your branches to all :( fixes stretch is shown only on the version where found.
So I would consider my help as half the job done.
