Problem counters With FXO cart

Hi,

I have Cisco Router 3945 with carts E1 and FXO. The version IOS is: c3900-universalk9-mz.SPA.152-2.T1.bin

The communication through E1 passed well without any problem. But I have some problem with FXO communication.

The problem that I have actually, when I start a call from IP phone to PSTN the counter displayed in the screen and begins calculating after that the user answer and he speak (for example, he told: ALLO).

If the user answers in this communication without speaking (told Allo) the counter don’t start in the IP phone.

My configuration FXO is:

!        

voice class custom-cptone omar

dualtone busy

frequency 425 425

cadence 500 500

dualtone ringback

frequency 425 425

cadence 1000 4000

dualtone reorder

frequency 425 425

cadence 250 250

dualtone out-of-service

frequency 425 425

cadence 320 320

dualtone disconnect

frequency 425 425

cadence 500 500

!    

!

voice-port 1/0/0

supervisory disconnect dualtone mid-call

supervisory answer dualtone sensitivity high

supervisory custom-cptone omar

supervisory dualtone-detect-params 67

no battery-reversal

timeouts interdigit 2

timeouts call-disconnect 0

timeouts wait-release 1

connection plar opx 5123

caller-id enable

!

Please, can you help me to resolve this problem?

Tanks in advanced,

Best Regards,

Omar

Hi Paolo,

Thanks for your update.

When I enter the command "no supervisory answer dualtone" in voice port, the counter begain when I  dial the number in my IP phone (in the moment of the ring tone and before the user answer in thecall ).

Do you have any other idea?

Thanks a lot,

Best Regards,

Omar

Re: Problem counters With FXO cart

There are only two options for two answer supervision on FXO ports:

1. voice-detection based answer supervsion, as per your original config (and it's working).

or

2. no answer supervision.

Choose one, or the other.

HI Paolo,

Thanks for your update.

Do you think that the problem is in the configuration of supervisory answer?

it's possible that the problem is lied in the configuration of supervisory custom-cptone?

what do you think?

Best regards,
