Cisco 7841 SIP phones dont accept digit while setting up the voicemail

[nitesz010]

Hello Everyone,

I am using CME-CUE with 7841 SIP phones. I have all the configurations done for the voicemail. When dialing into the voicemail, it starts with the prompt, " Welcome to CIsco Unity Express.......To record a new name press 1, to keep the recorded name press #." I doesn't take the keypad entry whether I press "1" or "#". The prompt continues and ends with the goodbye message. Please help.

Please share the configuration.

This looks like a DTMF configuration issue. For DTMF to work, you need the following

1. Configure DTMF for the phone

voice register pool xx
 dtmf-relay rtp-nte sip-kpml

2. Configure DTMF on the dial-peer to CUE
!
dial-peer voice xx voip
 session protocol sipv2
  dtmf-relay rtp-nte
  codec g711u

3.Configure DTMF in CUE
ccn subsy sip
dtmf-r rtp

Hi Deji, is latest CUE release supporting inband DTMF?

[Ayodeji Okanlawon]

Hi Vivek,

Yes it does.

As of five years ago, this threads indicates that it supports rfc2833

Thanks D (+5).

Thanks Ayodeji. I actually had the dtmf configurations mentioned above. To solve this issue I actually had to go the voice register pool XX and add dtmf-relay rtp-nte. I thought that would be by default. But I still have the MWI notification issue. I cant get the lamp or the envelope sign on when someone leaves a voice message. I am using SIP unsolicited method.

!
sip-ua
 mwi-server ipv4:x.x.x.x expires 3600 port 5060 transport udp unsolicited

(where x.x.x.x is the ip add of the unity express)

On the Unity Express side I have

ccn application ciscomwiapplication aa
 description "ciscomwiapplication"
 enabled
 maxsessions 10
 script "setmwi.aef"
 parameter "CallControlGroupID" "0"
 parameter "strMWI_OFF_DN" "8001"
 parameter "strMWI_ON_DN" "8000"
 end application

Moreover I have created two dn's for mwi on and off under telephony service.

ephone-dn  19
 number 8000.... no-reg both
 mwi on
!
ephone-dn  20
 number 8001.... no-reg both
 mwi off

You don't need mwi dn if you are using unsolicited. I believe this is used for outdial..the old method

You need mwi configured on the DN of the phone..
