outbound Auto Attendant not responding to dialed numbers

hey everyone...our setup is CUCM 7.x, H.323 gateway. When placeng calls to a company with an auto attendant, we get no response from their auto attendant when pressing the appropriate digits in their menu. When digits are pressed, the menu keeps playing as if nothing is happening. So, I would assume the tone signal is not coming through properly from our end. Any ideas? Thanks in advance.

Re: outbound Auto Attendant not responding to dialed numbers

Do you have the dtmf relay h245 alphanumeric configured in your dial-peers??

Re: outbound Auto Attendant not responding to dialed numbers

Nevermind, I understood it was your AA that was not responding.

Have you tested from other phones to confirm their AA recognizes the DTMFs? your mobile, your home phone?

This problem is usually on the other end so it's not something you can fix.

Do a simple test, dial 1-800-GOCISCO and try to use the options. If they work, you're sending the DTMFs.

Re: outbound Auto Attendant not responding to dialed numbers

Brandon.

You are missing the concept that Cisco gateways always match TWO dial-peers for every call that traverses the gateway:

http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a008010fed1.shtml

In your scenario for this call direction, you will match an inbound voip peer, and outbound POTS.

Try adding this:

dial-peer voice 555 voip

incoming called-number 91[2-9]..[2-9]......

  dtmf-relay h245-alpha

  codec

  no vad

Verify once the call is up that you match pid:555 on the top leg with 'sh call active voice br'.

What is likely currently happening, is you have no inbound peer defined, so we match pid 0 inbound, which doesn't have DTMF-relay capabilities.  You'd see that in the oubound TCS if you looked at the H245 messaging.

Brandon,

That's your problem.  CM doesn't support rtp-nte on H323 trunks.  This will fix it.
