OK, what is not working? What is happening?

Hi Chris,

When I shut the CUCM down, the phone is not registering to the Router.

Thanks

Does it have SRST reference defined?
Are you running SCCP or SIP load?

[Rajan R]

Yes, SRST ref is defined. Running SCCP load.

[Chris Deren]

Can you post "debug ephone register"?

Chris

[Rajan R]

I shutdown the call manager to get a few logs, but nothing.

I see nothing on for "debug ephone register"

Thanks

If you browse the IP address of the phone and go under Network Setup do you see the SRST reference there?

Can you ping the SRST router from the CUCM or the phone VLAN?

Chris

[Rajan R]

Yes, I can see the router IP Listed as SRST and aswell as on the "Device Config" on the phone.

I can ping it ofcourse, also the router is registered as a h323 gateway on cucm and pri calls are thru it.

Thanks

VR

[Chris Deren]

Are other device types registing to it?

You may want to do a wireshark trace on your PC to see what the IPC is doing.

Chris

[Rajan R]

No, none of em is.

I do see the request sent out to the router. I am still learning TS. Pls help out, I have attached it.

Thanks

Hi Chris,

I wrote the config and restarted the router and it started working. Didnt change a thing.

The phone has registered with the router.

I am not able to dial and working on a dial plan.. Do i need anything more ?

Thanks

VR

[Chris Deren]

What are you dialing? PSTN or internal numbers?

If PSTN please post "debug isdn q931" and "debug voice dialpeer"

HTH, please rate all useful posts!

Chris

[Rajan R]

Hi Chris,

I am dialling PSTN and it works now.

I have the below two dial-peers. I had "destination pattern ." on voip and had to remove it. But what will happen now when I turn the CUCM back on. Also what should I do for Internal Numbers ?

dial-peer voice 1 pots

destination-pattern 9T

direct-inward-dial

port 0/0/0:15
