CISCO 2901 as VOIP Gateway to VOXEO PROPHECY

[georgedimicro]

Hi

I have no experiance in Cisco 2901 router configuration. I am using VIC2-2FXO (2 analog ports) to connect to VOXEO Prophecy voice portal. As in VOXEO documentation described , I have to define Dial Peer to the IP address where Voxeo Prophecy Installed.

The problem is that when make a call from PSTN the line rings the specified number of rings and after that gives the busy tone.

Nothing is appearing in Voxeo Log relevant to the call.

Attached are the running configuration  and the a debug result when making the call.

Please any advice is highly appreciated.

No attachment!

Sorry , by mistake ,I press the "correct answer"

I was thinking so... how 'No attachment' could solve your issue :)

I assume that there is an incoming call on FXO port which you want to route it to VOXEO using SIP. True?

If that is the case, you need to define the number (destination-pattern) to be routed to VOXEO.

Lets say number is 1000...

Add 'connection plar 1000' command under voice-port x/y/z.

Add 'destination-pattern 1000' command under dial-peer voice 100 voip

Share the result then.

Thank you for your reply Vivek.

After doing what you propose I moved one step forward. Now I do not receive busy tone.As I can see in debug the "dial-peer voice 100 voip" is reached but

1. There is silence from the call

2. Nothing is appearing in Voxeo Log relevant to the call.

Attached are the running config and the debug output.

Thanks

Please add following commands and then share the output of debug ccsip messages; 

voice service voip
 sip
  bind control source-interface GigabitEthernet 0/0
  bind media source-interface GigabitEthernet 0/0
  early-offer forced
 

[georgedimicro]

sip bind commands ok.

Unable to run the "early-offer forced" command  in global or dial-peer mode.

dimicrocisco(config)#voice service voip

No success to reach Voxeo

Attached are the running config and the debug ccsip messages output.

Hi,

Configuration seems good now and router is sending INVITE too to VOXEO but there is no reply from VOXEO. We now need to check at VOXEO end why it's not replying to INVITE.

Thanks

Hi,

It works after changing the Voxeo config i.e. there was no default application and no application with address "7654@192.168.1.198". There is problem with disconnect when the inbound call from FXO goes on-hook. Then the FXO port remain open (busy tone) and the only way to go on-hook is to close the voxeo prophecy server. I have tried "Power Denial-based Supervisory Disconnect" and "Tone-based Supervisory Disconnect" with no success . The installed  VIC-2FXO does not support "Battery Reversal".  

Thanks
