How to configure Cisco Router T1 for MGCP
Below steps checked on Cisco 2811 and 2911 Routers
1- Check the VVIC location
R1#sh inventory
NAME: “2811 chassis”, DESCR: “2811 chassis”
PID: CISCO2811 , VID: V05 ,
NAME: “VWIC2-1MFT-T1/E1 – 1-Port RJ-48 Multiflex Trunk – T1/E1 on Slot 0 SubSlot 0“, DESCR: “VWIC2-1MFT-T1/E1 – 1-Port RJ-48 Multiflex Trunk – T1/E1”
Show inventory command shows you the location installed VVIC card in our case it is installed on Cisco Router Slot 0.
Call is connecting but phone is not ringing CCIE Voice LAB setup
I was trying to build the CCIE Voice lab for practice and learn Cisco Voice .I configured T1 connection from HQ site to PSTN T1 with tree channels .HQ site I had to configure HQ site MGCP with using three channels .I configured the MGCP on T1 line and it was registered in CUCM. I configured T1 line channels manually because i wanted to use 3 channels . as soon as i was applying the registering on cucm it was making it 24 channels . but T1 channels was up and multiple frame was established .when i was calling from HQ site to PSTN phone On the phone call was showing connected but PSTN phone was not ringing. I did the mistake on my PSTN router I did not configured following parameter. so it was not ringing my phone .
Below was the my configuration on HQ site and PSTN site .

Cisco CME SIP extension as X-lite Phone
1- Allows SIP phones to call other SIP phones and H323 calls
voice service voip
allow-connections sip to sip
allow-connections sip to H323
allow-connections H323 to sip
allow-connections H323 to H323
2- Enable IOS SIP Registrar
sip
registrar server expires max 1200 min 300
3- configure the voice register configuration The “voice register global” configuration is similar to the telephony-service configurations used for SCCP phones.
Cisco CME and ephone Button Command attributes
: Normal Ring
b Call waiting Beep No ring
f Feature Ring
m Monitor mode
o Overlay Line no call waiting
c Overlay Line with call waiting
x Overlay expansion /Roll over
s Silent Ring
w Watch mode
Button Number (Attribute ) Directory Number
For Example if we have to configure one line when call comes there are silent ring on button no 2 and ephone-dn 10
#button 2 s 10
How to configure Cisco router as NTP server
1- you have to obtain public NTP server addresses from www.ntp.org
2- configure you router with NTP server IP
GK_RTR#configure terminal
GK_RTR(config)#ntp server 64.209.210.20
GK_RTR(config)#ntp source lo
GK_RTR(config)# ntp master
GK_RTR(config)#clock timezone ARIZONA -7
3- Verifying NTP Configurations
GK_RTR#show ntp associations
GK_RTR#show clock
4- After you configure the Cisco router to synchronize with an NTP server, you can configure it to provide date and time information to a CUCM server and other devices,
Note :- If you want to allow your Router act as NTP server and specify specific interface to provide NTP services then you have to give command “ntp source ” before “ntp master” otherwise it will give NTP services from 127.0.0.1 .
Cisco Router as DHCP Server
Using a Cisco router as a DHCP server is a somewhat common practice in smaller networks.In this example we have two VLANs one for Voice and one for DATA.
DATA VLAN IP Nework Range 172.16.1.0 Gateway IP 172.16.1.1 DNS Server 10.31.144.1
Voice VLAN IP Nework Range 172.16.2.0 Gateway IP 172.16.2.1 DNS Server 10.31.144.1
TFTP Server for Cisco Phones 172.16.2.1
GK_RTR#configure terminal
GK_RTR(config)#ip dhcp excluded-address 172.16.1.1 172.16.1.9
GK_RTR(config)#ip dhcp excluded-address 172.16.2.1 172.16.2.9
GK_RTR(config)#ip dhcp pool DATA_SCOPE
GK_RTR(dhcp-config)#network 172.16.1.0 255.255.255.0
GK_RTR(dhcp-config)#default-router 172.16.1.1
GK_RTR(dhcp-config)#dns-server 10.31.144.1
GK_RTR(dhcp-config)#exit
GK_RTR(config)#ip dhcp pool VOICE_SCOPE
GK_RTR(dhcp-config)#network 172.16.2.0 255.255.255.0
GK_RTR(dhcp-config)#default-router 172.16.2.1
GK_RTR(dhcp-config)#option 150 ip 172.16.2.1
GK_RTR(dhcp-config)#dns-server 10.31.144.1
If you are using Windows server or some other centralized device for DHCP services. Even Cisco Unified Communications Manager includes DHCP server capabilities. you need to configure ip helper-address <central DHCP server IP address> to your VLAN interface to forward DHCP requests to the central DHCP server for the voice and Data VLANs.
