Hi all
I have a cisco 2811 router with pvdm2-32 and vwic2- 4FX0 and IOS version of Router is 15.01
when I use this router as a fxo gateway :
in outgoing calls , the Co line is occupying but no connection to called number is happening ,
just some noise but the line is busy so that no one can call this isdn number from outside
and when a incoming call comes from outside, nothing happens (debug on router shows nothing )
But when I use Grandstream FXO-gateway instead of cisco router , there is no problem and outgoing calls works very well
I got these information from the recorded voice call (which is dialed with Grandstream as FXo gateway)
Busy tone = 425
on time frequency = 500
off time frequency = 500
would you please help me to fix this probably with changing my router configration?
This is my config on 2811 :
