Does anybody know if AT&T using the 4ESS variant can enable guard time?

Looks like this thread drew some interest. The reason I brought it up is becase we have a client using an IVR application to call out to their customers. Since the answer mode is expecting a more standardized ringtone (on time and off time) the IVR does not work as expected. The client...

I've heard in Asia today, many people are using special ringtone to replace the traditional "too-too...", instead they can choose to play mp3 songs, or recorded greetings while waiting for someone to answer the call. It works like a PBX playing music on hold. This is not like changing your...

This is a voicexml question that I'm hoping somebody will know. Will grammars with fully qualified URI’s work within a Link element? I looked at the W3C specs and all the examples for Link element are using inline grammars. There is nothing stated that fully referenced URI in the src...

Yes, both sides can iterpret t.37

Hi, I'm running into a problem where a fax document gets elongated if the fax call goes out from the Avaya PBX8700 to a fax machine that is connected to the G700 VoIP pbx. -Fax is sent out from the PSTN. -The outgoing fax has some conversations: -The OPS protocol (using the PBX8700) is...

Anybody have any insights with possible size limitations with UUI data (User to User Interface). It's my understanding the size limit is 96 bytes but does this get set by some parameter or some other setting? Also, is there a specific field that holds this? I've read some documentation but...

I'm sure we all have encountered the infamous "If you like to make a call please hang up and try again. If you need help dial your operator" prompt. A high pitch sqeal is hear just prior to the prompt being played. I'm curious as to why a caller would encounter this. I hear this at...

Have an IVR box with a Voice card (NMS) that uses a built in echo cancellor. It appears we still hear a very noticeable echo on the lines that impact Speech Recognition. I assume echo can be cancelled in other areas of the Telco infrastructure. For example, do certain switches have a built in...

Any ideas on why an IVR Speech Reco application prompt would barge in on the call. It only happens to specific number on the T1. I already rolled the trunks (1&2) and the problem followed the line. So I know the problem is somewhere in the Telco infrastructure. Anybody have any ideas?

Anybody know why an IVR prompt would barge in on a Speech Reco application. Echo Cancellation is enabled in Nuance, the NMS voice card and the IVR but it appears calls to a specific line on a T1 (line 14) will have this problem. It does not happen on any other lines of the T1. Just this one...

The IVR system is connected to a T1. Callers are calling from analog and digital phones from different areas (in and outside of the state). So the calls go across the Public Netork.

Thanks for the response. The IVR uses an NMS voice card (and AG4000 2T to be exact) and a T1 is used (OPS). We've already ruled the card out by swapping a different NMS board (it's highly unlikely they have two bad baords). So I agree that there can be bad circuits from the T1. Thanks again.

Can anybody provide me some insights on causes for low volume with callers who call into an IVR system. We have recorded utterances of callers with very apparent low volume. These callers originate from out of the state so I suspect it has something to do in the Public Netork. Unfortuneatly...
