h245-alphanumeric on UCM 6.0.1(a) not work

Unanswered Question

Hello all!

[ISP]---[3845-IP2IP-GW]---[CCM]

I have a strange problem with my UCM 6.0.1(a) When I call to outside from ip-phone, I can't work with IVR and dial extension number (for example I call 97273565 and dial ext 233 after connect).

I run debug on 3845:

debug h245 asn1

"value MultimediaSystemControlMessage ::= indication : userInput : signal :

{

signalType "2"

duration 100

}

"

It is example - other dialed digit were also recognized. So, I saw that my ip-phone sended dtmf to 3845 in dtmf-relay h245-signal.

So, why my ip-phone (7911) send DTMF in signal mode?

On CCM 3845 register as h323 GW with unchecked "Wait for Far End H.245 Terminal Capability Set", set "MTP requared", checked "Enable Inbound FastStart". Other sets by default, "Media Resource Group List" - using CCM's MOH_2 and MTP_2 without multicast.

If I call from FXS-port on 3845 to outside - dtmf send as alphanumeric.

Please help!

So, if you change the dtmf on the dial-peer that is handling the call to h245-signal, are you able to handle the IVR options?

CallManager support incoming H245 alphanumeric

but sends h245-signal.
