You should consider registering your VG224 analog ports as SCCP endpoints in the CCME. This will allow supplementary-services to be extended to these ports. See this document:


Your other option is to run a the app_h450_transfer tcl script on the VG224. That will allow you to perform hookflash transfers on your analog ports.

For this option, see this document:


I've done both methods, and I would suggest that you enable SCCP control and let CCME extend the supplementary services.

i have tried to configure VG224 as a SCCP gateway.what i have done is:

#conf t

#sccp local

#sccp ccm identifier 1 version 3.3


#sccp ccm group

#associate ccm 1 priority 1


When i have typed the "#show sccp" command;

this message shows....

"sccp parameters are not activated (dspfarm profiles)or not associated with ccm group"

Then i came to know that dsp farm needs to be created.

I have dsp module in CCME router...

But what i have to do to integrate this ....???

Can you please give me the detailed configuration steps...???

i am stuck with this........

please please help me.........

Thanks in advance.........

Here is the document which explains to create a dsp farm.

The information in this document is based on these software and hardware versions:

Cisco CallManager version 4.0(1)

Cisco IOS Software Release 12.2(15)T13 IP Plus

Cisco 2651 Gateway

NM-HDV with two Packet Voice DSP Module (PVDM) DSP Single In-line Memory Modules (SIMMS)

I am facing the same situation where I have a CCME with VG224 configured as H.323 peer and not SCCP (we had to since we dont have free ports on the CCME).

I wish to initiate a call transfer from an analog phone connected to the VG224 by using the second method (the script, hookflash).

I have downloaded the app-h450-transfer. script and copied it to the flash of the VG224.

The following is my configuration on the VG224:


service transfer slot0:app-h450-transfer.

paramspace english language 1

dial-peer voice 11 pots

corlist incoming BAC-CSS-GSM

corlist outgoing call-Internal

description --- science lab

service transfer

destination-pattern 3341

port 2/1

where the phone is connected to port 2/1

I have loaded the application (call application voice load transfer)

I still can not transfer a call from an analog phone.

Am I missing something in the config?

How did u get it work by using the tcl script?

I would be very thankful if you can help me on this issue.
