Bell ringing but no voice

Hi i have just installed ccm 4.1.2. I successfully registered 3 ip phones

1. 7940 ip address 10.1.1.30

2. 7940 ip address 192.168.0.50

3. 30 Vip ip address 192.168.1.30

Above three phones are in different location as you can see above subnet.

=> From 1 i can call 2 and vice versa. Both can receive and make calls but cant here.

=> From 1 and 2 unable to make and receive calls to 3 or from 3 unable to make and receive calls.

Any Expert Suggestion

Re: Bell ringing but no voice

Almost sounds like a routing issue, can all the subnet ping each other? Are you using a routing protocol or ststic routes?

Re: Bell ringing but no voice

I agree sounds like a routing issue. It seems that phone 1 and phone 2 can reach the callmanager subnet but not each other's subnet. Signalling (rings) is between the CM and phones and RTP stream (voice) is between the phones.

Re: Bell ringing but no voice

I am using static routes. My call manager ip address is 192.168.2.150. I did port forwarding to the call manager.

=============================================

static (inside,outside) udp interface tftp 192.168.2.150 tftp netmask 255.255.255.255 0 0

static (inside,outside) tcp interface 69 192.168.2.150 69 netmask 255.255.255.255 0 0

static (inside,outside) tcp interface www 192.168.2.150 www netmask 255.255.255.255 0 0

static (inside,outside) tcp interface 2000 192.168.2.150 2000 netmask 255.255.255.255 0 0

static (inside,outside) tcp interface 3389 192.168.2.150 3389 netmask 255.255.255.255 0 0

access-list inbound permit tcp any any eq 69

access-list inbound permit udp any any eq tftp

access-list inbound permit tcp any any eq 2000

access-list inbound permit tcp any any eq 3389

access-list outbound permit udp host 192.168.2.150 host 61.29.0.0 eq tftp

access-list outbound permit tcp host 192.168.2.150 host 61.29.0.0 eq 69

=============================================

Any Suggestion please.

Re: Bell ringing but no voice

Hi,

You dont give us enough info to solve your problem.

Looks like you have PIX at main site, and there are two branchs. And you set up IPSEC-Tunnel between main and two branchs. Am I Right??

If you have PIX at main site, then make sure the version has to be 7.0 above. It is because old verison wont send traffic out at the same interface.

Please see attachment and rate the post.

Ken

P.S. Correct me If I am wrong with your topology.

Re: Bell ringing but no voice

Thanks for reply. No there are no branches at this stage, previously there was vpn tunnel between two branches. But now there is no more tunnels.

Any Specific reason.

Thanks
