Unable to Dial Once Connected to a Conference

Andrew Mathu
Level 1
Level 1

Hi Guys,

Once I dial into any conference, I am unable to enter the digits if I am prompted to.

E.g I dial Cisco TAC support, and I am told to press 1 to record a message. I press the 1 but there is no response.

I have two voice routers connected to each other.

On one of the voice routers (Router 1), there is an E1 line terminated on it. The config is as below:

Router 1:

dial-peer voice 4 pots
description TELKOM DIALPEER
destination-pattern 9.T
incoming called-number 9T
direct-inward-dial
port 0/3/0:15

The connection between the two router is as below:

Router 1 (IP address 10.10.10.1):

dial-peer voice 1 voip

description INTERNAL_CATALYST_VOIP

destination-pattern .00

session target ipv4:192.168.10.1

dtmf-relay rtp-nte

codec g711ulaw

Router 2: (IP address 192.168.10.1)

dial-peer voice 3 voip

description PSTN_GATEWAY

destination-pattern 9.T

session target ipv4:10.10.10.1

incoming called-number .

dtmf-relay rtp-nte

codec g711ulaw

What could be issue. I have tried all avariants of dtmf i.e. h245-signal h245-alphanumeric cisco-rtp and even combined them variously but to no avail.

I've also added the command: voice rtp send-recv.

WHAT COULD BE THE ISSUE?

Sounds like you need MTP (Media termination point) to carry the DTMF from your keypad through to the service to commit a selection

Hi,

How do I Configure the MTP?

Hi,

Let me take a look.

Thanks.

Andrew before you configure an MTP you should understand your call flow..

Your DTMF config are wrong. You shoudlnt use rtp-nte on a h323 dial-peer, cisco doesnt support that. It is supported on a sip dial-peer..

Can you describe your call flow and waht phone models are you using?

IP phone--CUCM---h323--gateway--E1?

Hi,

The call flow is as below:

Cisco IP Phone ---------->Cisco Call Manager EXPRESS---------->Cisco Call Manager EXPRESS(E1 is here)

You need to configure an inbound dial-peer on the second cucm express. Ensure you have dtmf-relay h245-alphanumeric on it..

Can you attach the config for both ccme
