[cisco-voip] Call can't get through PBX's Automated-Attendant

[Turpin, Mark]

So DTMF relay has to do with the VOIP legs and if you've got IOS GW2
setup to be VOIP between PBX2 and GW1 then you first need to make sure
you have CUBE features enabled.  Second, you should be able to use debug
voip dialpeer all and/or debug voip ccapi inout to see the digits being
passed by the PBX2 to GW2 and out to GW1.

 

Once they get to GW1, there's nothing to configure on the POTS because
DTMF is going to be played in-band.

Hi All,

 

pls refer to the below simple topology and description:

1. PBX(2) conncted to GW(2) via H.323 trunk thru LAN connection

2. GW2 use H.323 trunk to GW1 thru WAN connection

3. GW1 use E1 (ISDN PRI) to PBX(1)

4. PBX(1) has AA enabled

 

     ------------            ----------------
----------------                    ------------

8-- | PBX(1)| --[E1]-- | IOS GW(1)| ----[WAN]---- | IOS GW(2)|
----[LAN]---- | PBX(2)| --8

     ------------            ----------------
----------------                    ------------

 

   <------------------------------------------- call flow
--------------------------------------------------

 

 

the problem now is.. when PBX(2) phone calls to PBX(1) phone, it can
hear the AA prompt, but after dialing the extension number, the call
just dropped..

I thought it's something about the DTMF relay, and I'm using out-of-band
relay (dtmf-relay h245-alphanumeric) in GW(2) dial-peer configuration
but still not working.

does anyone has any suggestion? or which debug command I can use in both
GWs to make sure at what point the extension digits been dropped..

 

Many many thanks for the help.

 

Regards,

Alan
