Analog DID Single Digit/Fast Busy

Hello All,

I am working to switch some AT&T analog DID lines from an existing Nortel PBX to a my Cisco 2921 with an H323 setup back to CUCM 8.6. Calls to the old PBX worked fine. After switch to the Cisco setup calls come in with a single digit (only the last digit, instead of the 3 we are expecting).

We have tried changing multiple timers but can't get the system to recoginize more digits. I have the settings from the Old PBX and they are the following:

E&M Wink Start

Incoming Disconnect (msec): 500

Incoming Dial Guard (msec): 70

Incoming Seizure(msec):500

Flash Length(msec):540

Incoming Incomplete Dial Alarm(sec) 255

End to End Signaling

Tone(msec): 350

Pause (msec):150

Here is the output from a debug VPM signal on an inbound call.

We have listened on the line with a butt set and can hear pulses on the line. We opened a TAC case and tac is claiming that the EVM 8FXS DID does not support pulse dialing, however when we connected a butt sett to the line and set it to pulse dial we are able to succussefully dial through the system and get to the CallManager/IP Phone.

Any ideas?

The pulses you hear are likely the winks. Telco would not dial both pulses and dtmf. If you can have this working it will be with appropriate settings, e.g. you can try immediate delay instead of wink start.
