PPM / Feature Buttons not working on Avaya SIP phones

This one was very frustrating. My SIP phones could log into the SBC-E and got dialtone fine, but wouldn’t pull PPM. The Avaya One-X Communicator for iPhone could do it though. Whaaaaa??

I have my phones configured to pull a config file from a web server – it’s the only manual setting required in the phone. All other settings are in the config file on the web. Well, it turns out that the phone didn’t like the SET CONFIG_SERVER w.x.y.z parameter. Once I removed that, then PPM flowed just fine.

By the way, if you have trouble with feature buttons, the other issue I had was the entity link between Session Manager and the SBC. If your’re using TLS connections between the phone and the SBC, then you also need to use TLS on the entity link between the SBC and the Session Manager, and the Session Manager to the Communication Manager. In other words, all connections from the endpoint to the CM need to be TLS. If any of them go back to unencrypted TCP or UDP, then the PPM breaks. At least it did for me!

Unable to log into the Avaya Utility Server as cust or admin on System Platform

I recently had a strange issue with my utility servers. I have four of them on System Platform on the S8300D servers. But I was unable to log into any of them as cust nor admin. I could log into my standalone utility servers, but not the ones on system platform.

It turns our the ldap config was corrupted on the servers and Avaya needed to fix it. Once complete, the tech sent me a nice summary:

If this were to happen again, you can verify if the account works by attempting login to SSH of Dom0 or Cdom or webconsole of Cdom.  If it works there, then we know that LDAP configuration is corrupted and needs to be corrected.  If it happens again, have a ticket open stating that LDAP is corrupted on VUS and that /etc/ldap.conf and /etc/nsswitch.conf need to be fixed.
