Dial-peer from pstn cant reach cucm

rahimamir67623
Level 1
Level 1

can someone help me what the issue is with my dial-peers, and to why i cant reach the extension numbers 6001,2,3 on cucm from the pstn, 

 

Router1 connected to the cucm server has a dial-peer as followed

dial-peer voice 1 voip

destination-pattern 10201020

session target voip ipv4:192.168.30.41

dtfm-relay h245-alphanumeric

preference 0

no vad

 

dial-peer voice 2 pots

destination-pattern .T

port 0/0/0:15

 

note: i can reach the ip phone (999) and the analog phone (991) connected to the router2 that is acting as my pstn  from the cucm but thats not the case in the other way round. Im using h323 as my gateway in cucm.

Hi,

I hope I understand your scenario correctly. The extension 991 on Router-2 is acting as PSTN and extensions 6001, 6002 and 6003 are registered with CUCM. You are trying to call from 991 to CUCM extension 600X. If this is the case, please verify following items:

  1. You have correctly configured H.323 gateway on CUCM with correct Calling Search Space (CSS) for inbound calls. Make sure this CSS can reach extensions 600X.
  2. Verify below configuration on Router-2: 
voice service voip
 ip address trusted list
  ipv4 0.0.0.0 0.0.0.0
 allow-connections h323 to h323

If it still doesn't work then please post the logs for following commands:

debug voip ccapi inout
debug h225 events
debug h225 asn1
debug dial-peer

Note: for router-2 I don’t have voice service voip neither a h323 configured, could that be the issue to why I can’t call from the pstn. I also don’t have voice class and css configured in cucm either, for router 2 it is CME and there’s no voice class

If this is not enough, I will post the full config when I get home.

Hi,

Can you please put together your scenario in a diagram to understand it better and help you resolve the issue?

Hi,

It looks like this is your lab environment. There are many issues with the configuration:

1. Same IP Address on Router-1 and Router-2

Router-1

 

interface FastEthernet0/0.10
description CONNECTION FOR VOICE VLAN
encapsulation dot1Q 10
ip address 192.168.10.1 255.255.255.0
h323-gateway voip interface
h323-gateway voip bind srcaddr 192.168.10.1
!
interface FastEthernet0/0.20
description CONNECTION FOR DATA VLAN
encapsulation dot1Q 20
ip address 192.168.20.1 255.255.255.0
!

Router-2

 

interface Vlan10
ip address 192.168.10.1 255.255.255.0
!
interface Vlan20
ip address 192.168.20.1 255.255.255.0
!

 

2.  Same CME IP Address on both Routers:

Router-1

 

voice register global
mode cme
source-address 192.168.10.1 port 5060

!

Router-2

 

telephony-service
max-ephones 10
max-dn 10
ip source-address 192.168.10.1 port 2000

!

 

3. In your post, you mentioned that the extension 6001, 6002 and 6003 are registered with CUCM. But as per below configuration, extension 6001 is configured on Router-1

 

Router-1


voice register dn 1
number 6001
name Kulan
label Kulan 6001
!
voice register pool 1
id mac 1CAA.0711.325F
type 9971
number 1 dn 1
dtmf-relay rtp-nte sip-notify
description 02077336001
!

 

4. From configuration, it looks like you are using switch module on Router-2 and connecting switch port FastEthernet0/3/1 on Router-2 to  FastEthernet0/1 Router-1. This seems to be a switching access port with only VLAN 30 allowed on it.

 

What you are trying to achieve is not going to work with this configuration. You need to streamline your scenario with proper connections, IP Addressing schema and IP Routing.

Thanks, Vaijanath S.

same ip add on router 1 and 2:-
they have the same ip address but would you say that would be an issue
since they are configured on seperate routers.

same CME IP Address on both routers:-
for router 1 i registered sip 9971 phone as a cme in my previous lab but then moved
the phones to cucm, so that config is no more relevent.


Yes, in my post i did mention 6001, 2 and 3 and that is in cucm, for router-1
my phones are rigestered through the call manager, i moved away from the cme in
router-1, this was a previous lab sorry for not letting you know


About vlan 30, this was another lab i tried, i setted up both routers as CME
and i was able to route calls from both sides through the pstn and wan link(vlan 30)


how would you configured the pstn that has a switch module card and you would
want to reach an ip phone number on the cucm?

in this dial-peer voip below where we have the ip address of the cucm, doesnt this
dial-peer needs to be first pointed to the cube, how is it going to reach the cube
from the pstn?
dial-peer voice 1 voip
destination-pattern 6...$
session target ipv4:192.168.30.41
dtmf-relay h245-alphanumeric
no vad

does router-2 acting as a pstn require a h323 to be configured as well since i have
router-1 configured as h323?
CUCM Server <---> router-1 (cube) <------> router-2 (CME)


thank you very much, i appricaite your help
