We had stability issues with Alcatel-Lucent OmniSwitch Ethernet Switches 6250. One issue is with licensing. When migrating from TDM to VoIP/ToIP solutions integrated on the same architecture, Alcatel-Lucent OmniSwitch Ethernet Switches don't have the same skill level or follow the same development path as companies like Cisco. They started integrating these solutions later, which is why there's a noticeable difference in advancement. Their main focus has been IP PBX solutions like OXO and OXE. They developed their IP environment and switches later, but not as deeply as other vendors. For example, they use Aruba access points and controllers for wireless solutions rather than developing their own portfolio. A specific challenge I've faced is with access points. Due to country code restrictions, the model sold in one region (like Europe) may not work properly in another. This affects channels and features related to the electronic environment specific to each country. To resolve this issue, I've had to reconfigure access points with the correct country code. The solution uses basic protocols. It doesn't have proprietary features like Cisco's EIGRP or advanced BGP features; it's based on standard protocols.
