[cisco-voip] ATA integrated with Cisco Call Manager

[Brain Whistler]

Hi,

I have integrated ATA 186 with Cisco Call Manager
using SCCP, both of its port are registered and have
seperate DN number. The problem i am facing is that I
can only receive and send calls through only one port,
its second port never worked, although I can see it is
registered to call Manager. 

Does anyone have idea what's wrong with it.

Thanks
Brain
