Outbound Call Dropped

[Guest TheyCalled Paul]

Hi,

We had a new customer today. A call come into our platform and then we place a call and connect them. When we call his phone numbers, sometimes the calls go through and sometimes the calls just drop. We checked with the targets telco and they confirm that sometimes they will the call and others they do not. Our dialing technology has been stable for years so we are confused. If you search the log for 6022981390 you should be able to see the dropped calls. If we call his cell phone - its fine. I believe this sample is when the call drop in a split second

 

I dont know how log space

The ktTel trace shows that on the call at 16:45:54 after dialing the Dialogic card reported receiving the "Proceeding" ISDN message. The Proceeding message would have been sent by the Telco's Switch.

 

Half a second later the Disconnect message is reported by the Dialogic card.

 

You would really need to get the Telco to do an ISDN level trace on the line to confirm whether their switch is sending the Disconnect message, and if yes then the Telco should explain why their switch is sending that Disconnect message.
