My client has take ten ELESIGN VOIP Gateway ESC1702 from KOREAN. But they didn’t take any manual about this equipment . They need to change some
configuration but they didn’t know how to config them. My client ask me if I can help them.
So I need the ESC1702’s electronic technical documents and other interrelated information.
Thank you very much for your help.
