Initial Delay Problem with Callee Type Detection Enabled

[dbachhawat]

Hi Plum Support,

Yesterday we tested our outbound IVR application and it worked well. For example, when the phone would ring, I would pick up and I would hear the initial prompt within about 1-2 seconds which was fine. However, today we had callee type detection turned ENABLED (yesterday it was DISABLED). With callee type detection enabled, I tested the exact same script. When I pick up the phone, the initial delay in hearing the first prompt is now 6-8 seconds. A delay of this length for the initial prompt of the VXML script will cause recipients of these calls to hang up because they will say "Hello" multiple times and not hear anything. This delay would be unacceptable for any outbound IVR system. On the other hand, callee type detection is important because how else can we recognize answering machines / voice mail (which is also an important feature so we can leave a message)? How can we reconcile these conflicting but basic needs? I'm assuming there must be a way to do it because both of these are absolutely basic outbound IVR functions. With callee type detection enabled, is there anyway to shorten the initial delay? Can you provide some example code of how this has been accomplished or point me to some appropriate resources?

Thank you.

Hi,

About your questions on callee type detection delay, you should only be experiencing a delay of about 1-3 seconds if your initial prompt is a non-bargeable prompt.

If you can provide us with the code you are using for your application, perhaps we can make some suggestions as to how we can improve the application,

Hi,

I've tested this simple script and the initial delay is still about 5-6 seconds long. Can you please test this message through our account and help us figure out the cause of this delay?

Hi,

We've tested your script within your hosted account. We tested this by calling a LAN telephone line as well as different cell phones. All of the calls lasted between 2-3 seconds. Is there any other information that would help us reproduce this situation?
