Does anybody know the reason why the IP Phone 1608 cannot establish connection with the IPO 406 Version 2 over a distance. The situation and set-up we have are the following:
- 2 POE switches between 2 buildings connected via a 1800 ft single-mode fiber trunk.
- The main building switch has a link to the IPO 406.
- The 1608 IP Phones work fine in the main building, but cannot find router (IP 406) once moved over to the second building.
- Other Avaya 5610 IP Phones work fine in the second building.
