[cisco-voip] Gateway / Gatekeeper Dial Tone Qestions

[Ryan Ratliff]

What is your connection to the PBX?  Simply do not configure 'direct- 
inward-dial' on the default pots dial-peer for the pbx connection and  
the router will play dial tone to collect digits before routing the  
call.   You'll then want to probably use cor to route all calls from  
that pots dial-peer to hit a voip dial-peer pointing to the  
gatekeeper (session target ras).   Then route the call in the  
gatekeeper and have the appropriate dial-peers on both gateways to  
send the call to the correct destination.

Dear All,

The planned topology is as below:

<PSTN>----PBXA----GatewayA----Gatekeeper ----<IP Network>----- 
GatewayB------PBXB-----<PSTN>
                     
|                                                                        
                            |
                  
PhoneA                                                                   
                     PhoneB

now I would like gatekeepr to perform the whole call routing control,  
for example: when PhoneA dial a number (even the POTS number), the  
call will go to GatewayA and provide the dial tone to phoneA, and  
then GatewayA query Gatekeeper for call routing decision, if  
Gatekeeper decide the number belongs to local PSTN, it will direct  
the call back to GatewayA; and if Gatekeeper decide the number  
belongs to remote PSTN, it will direct the call to GatewayB.

I'm not sure if this design will be working, but I'm wondering if  
Gateway can provide the dial tone to PBX connected phone. Does anyone  
have clue about it? Thanks in advance for your kind help.


Regards,
Alan
