How is your gateway configured? Can you send a sh run of your gateway

[Devendra Somankar]

attached is the config for 1st 2951 gateway.Another 2951 gateway is also configured same way.In each GW 5 E1-PRI are configured.

[Ayodeji Okanlawon]

Please add the following to your config..

dial-peer voice 1 voip

dtmf-relay h245-alpha

incoming called number .

no vad

[Devendra Somankar]

Its MGCP Gateway configured..Route patterns are configured in CUCM.Still need to add voip dial-peer?

[Ayodeji Okanlawon]

This is why I asked how is your gateway configured..I can see h323 configuration as well as MGCP..

interface GigabitEthernet0/1
description VOICEGW MAIN INTERFACE
ip address 10.222.1.18 255.255.255.0
duplex auto
speed auto
h323-gateway voip interface
h323-gateway voip bind srcaddr 10.222.1.18
!
 

Ok please add this to your config

mgcp dtmf-relay voip codec all mode nte-ca

mgcp package-capability fm-package
mgcp package-capability dtmf-package

Then reset mgcp..on the gateway

no mgcp

mgcp

Hi

Actually this problem was on SIP call,User was dialing shortcode and it was going through their SIP trunk, raised case with TAC and they replied "its expected behavior and documented in the release guides, we do not find any defects filed to fix this. we are hoping, this behavioral change would be included in the future releases"

• version of call manager  9.1.2.11900-12
• current firmware running on the phone-SIP 9.3.3.5

Hi All,

If anyone can help,

i have two cp8831 and 10 Cp8841 at the same site all registered as sip

i have same ext# 10000 configured on one  8831 and one  8841

I have a sprint conference bridge number, if i dial it form 8831 it does not accept DTMF input. at the same time if i use the same number on 8841 that works and infact on all the 8841 works

if i dial a skype bridge number on 8831 that works too on both the phone 8831 and 8841

any suggestions what i can test on 8831 why is it not accepting the DTMf input.

regards

Ravi
