Disconnect Cause Value=3

Hi All,

I have some problem with my H323 Gateway

existing topology is Call Manager - PABX - H323 gateway, now my customer want to dismantle PABX. so, H323 gateway will be directly attached to Call Manager.

when i place a call with existing topology, it's success, but with new topology, it failed with disconnect cause value =3 (no route to destination).

There is no change of configuration in gateway side. I just register H323 gateway to call manager and then create route pattern to that H323 gateway.

i make sample call scenario for debug isdn q931 and debug voip ccapi inout

calling number = 53319

called number = 457104

when i debug the h323 gateway, the router receive 457104 digits from both call through pabx and call manager direct to h323 gateway.

if i call from call manager direct to h323 gateway, router send disconnect cause value = 3 and terminate the call but if i call from call manager through pabx, it will be success because match with dial-peer 457.

Why call that direct to h323 gateway failed (dest cause value 3) if there is dial-peer to route the call (dial-peer 457)?

please find attached debug file from both condition.

Thanks,

Helmi

Disconnect Cause Value=3

Helmi,

in that case, it is voip dial-peer between CUCM and H.323 GW(A) and another voip dial-peer to 2nd H.323(B)

you don't have IP to IP functionality configured in H.323(A) and hence it won't work.

when you have the PBX, it is POTS dial-peer to H.323(A).

you would need to go for CUBE functionality if you want to connect the CUCM when dismantling the PBX connection.

Try to define as below in both gateways.

voice service voip

allow-connections h323 t h323

Disconnect Cause Value=3

Hi Suresh,

I configure voip dial-peer because the call (4571504) will be sent to other h323 gateway ( 146.40.74.124 ) not to PSTN.

Re: Disconnect Cause Value=3

Hi Nishant, Hi Suresh

Really appreciate for your help.. it's working well right now after i configure allow-connections h323 to h323 on the H.323 router and uncheck Wait for Far End H.245 Terminal Capability Set in H.323 gateway on Call Manager.

.

Many Thanks,

Helmi
