VG224 and broadcast tool STI 2 interface


I am looking for a VG224 configuration in order to use a Broadcast tools STI 2 interface (it is an auto-answer interface:

I have a VG224 configuration in SCCP protocol which works but not with a recent VG224 (there are 1 or 2 years apart).

Is there any change of component between two series of VG224?

I put the same configuration on two VG224. With the old one, the STI interface detects the ring tone and it picks up the call. With a recent VG224, the STI interface do not detects the ring tone.

Someone has already use a Broadcast Tools interface?

Thanks for your help

Did you try measuring the idle and ring voltages on the 2 different VG224s and see if there is any difference?  Are they both running the same code version as well?  How about hardware revision?

Thanks Brian for your answer

Thanks Brian for your answer.

I use the same IOS, vg224-i6s-mz.151-4.M5. It is the same hardware revision.

Tomorrow, I will try to do the measure between the two VG224.

Multimeter should be on DC

Multimeter should be on DC voltage for measuring idle voltage I believe and then on AC for measuring ringing voltage.

I tried with a VG202. The STI

I tried with a VG202. The STI 2 interface detects the calls but it fails to pick up and I have this logs on the VG202 prompt :

*Mar  1 01:03:39.879: Power alarm on DSP channel ch=129 is ON
0001 0001 **

*Mar  1 01:03:40.891: Power alarm on DSP channel ch=129 is OFF
0001 0000 **

I will get an oscilloscope tomorrow to do the measure on the VG224 gateways.

Yes, I found it also.To run

Yes, I found it also.

To run the VG202 with the STI 2 interface :

- I disable a parameter on the STI 2 interface: CPC (Calling party control).

- I configure the VG202 in SCCP in 15.1(4)M8

- the voice port configuration is:

voice-port 0/1
 ring frequency 50
 no battery-reversal
 compand-type a-law
 cptone FR
 timeouts initial 60
 timeouts interdigit 60
 timeouts ringing infinity


So is that working now then?
