We have 10 phone extensions that instead of gettings messages on the phone, we configured the Avaya IP Office to forward messages to a specific email for each extension. The SMTP server adress is specified in avaya settings and a local Windows server IIS 6.0 SMTP service. This has been working well for years.

Since yesterday the emails are no longer being sent. I rebooted the Avaya system a few time, and everytime the emails work for the 5-10 first minutes. I am in the dark here. How do I diagnostic this problem, I am not sure what I am looking for?

  • I rebooted the Avaya Switch at least 4 times, same results
  • I rebooted my DC/DNS/SMTP server
  • I tried to look at SMTP logs, Firewall logs, Event logs
  • I am able to ping the avaya switch, it's on the same subnet
  • The SMTP seems to work, whenever I put a file in my SMTP C:\inetpub\mailroot\Pickup it is sent right away.

Any suggestions?

The problem was that the communication between the phone switch and the SMTP server was interrupted because of an IP adress conflict. A second internet line and modem was added a few weeks ago but not configured correctly, so its DHCP started to generate conflicting IPs. That explains why the system could work for a few minutes after a reboot, it was until the configuration spread to the network.

Since I could not find the option to deactivate the DHCP on the new modem, I unplugged it until I have the time to configure it correctly. Everything is back to normal.
