SIP INCOMING CALLS NOT WORKING

Hi

Setup:

ISP SIP--> VG SIP--> CUCM- Extensions

Sip Trunk in CUCM: Destination Port 5080 (Requested by ISP)

Below is the trace

Calling number:22551286

Called number:00302155203740

Extension:2803

CUCMs: 192.168.1.241 , 192.168.1.242

ISP network:10.224.71.68

In my interface connected with ISP modem:192.168.10.253

Problem::

Incoming calls never going to the extension number:

If i try to bind SIP  media and call control then i lose the registration with ISP.

So i dont use sip binds

Trace shows that CM takes and ansewr the calls, so you should  look what's happening there.

Hi Paolo

I saw that , but the calls never coming to the extension.This is the strange

In the sip trunk config in CUCM i have 4 significant digits and the CSS include the PT for my extension

When i shut the sip dial peers in VG and no shut to the h323 dial peers then the phone ringing

(With H323 we have other problem and this is the reason that i tried to check the sip

With H323 when i answer the call its stay active ONLY for 10 sec.And then its going down

Any ideas FOR all ?

Hi

10.93.7.245 is the voice ip in the ISP Modem

10.93.7.245 is not in the same subnet as 192.168.10.253. I suspect there is NAT in there. Is that your router or their ?

Also, I don't understand why there is session progress coming in after invite.

192.168.10.0 subnet is in the modem site(ISP) for private ip

192.168.10.253 in in my interface .254 is in the modem side

The above is a private network that gives the ISP throught the modem

Now they have also configure in their modem 10.93.7.0.245 which is the voice ip.In this connection they will pass internet and also voice

So they have different subnets configured for that

ip route 10.93.7.0 255.255.255.0 192.168.10.254

ip route 10.199.0.0 255.255.255.0 10.100.0.4

ip route 10.224.50.0 255.255.255.0 192.168.10.254

ip route 10.224.64.0 255.255.255.0 192.168.10.254

ip route 10.224.71.0 255.255.255.0 192.168.10.254

ip route 10.224.75.0 255.255.255.0 192.168.10.254

ip route 192.168.10.0 255.255.255.0 192.168.10.254

I spoke with the ISP and they said that they see the invite for my extension

Is it normal?

i am not sure about that

Please rate all useful posts Regards Chrysostomos ""The Most Successful People Are Those Who Are Good At Plan B""

In my expereince, one has to focus on the very first message that doesn't look normal, and that is the session progress above.

In CUCM, what is the address of SIP trunk, or H.323 GW ?


For sip trunk i used 10.110.0.3 :

Also 10.110.0.3 is binding in this router for the h323 communication (existing setup)

!

interface Loopback0

ip address 10.110.0.3 255.255.255.255

h323-gateway voip interface

h323-gateway voip bind srcaddr 10.110.0.3

!

Please rate all useful posts Regards Chrysostomos ""The Most Successful People Are Those Who Are Good At Plan B""

Please replace that with VG local interface address. Also  please configure VG for media flow-throgh, not flow-around.

Hi

Thank you for the replies

i used the voice subinterface but the same results..

!

interface GigabitEthernet0/2.20

description ##### VOICE Vlan #####

encapsulation dot1Q 20

ip address 10.17.20.1 255.255.255.0

ip flow ingress

ip flow egress

!

Do you have any ideas?

Its really very strange

Please rate all useful posts Regards Chrysostomos ""The Most Successful People Are Those Who Are Good At Plan B""

You should have a router interface on subnet common to CM LAN interface.

Please use that and configure the corresponding address in CM.

Paolo

Its a remote site (SRST SITE) which the phones registered to cucm.The communcation is via tunnel

Please rate all useful posts Regards Chrysostomos ""The Most Successful People Are Those Who Are Good At Plan B""

It seems to me there is some confusion, You would have to include a diagram with all the circuits, devices and addresses.

I also noticed in your trace that there is no "Trying" received from cucm before the "session progress".....

When CUBE sent an invite to cucm, the first response should be "trying" Thats how cucm says i am going to look for the number....Are you sending the full trace? If you are then something is wrong with the way CUCM is processing the sip invite
