I believe those IEC are being generated by the IOS post receiving a disconnect with PI -

015408: Mar 22 11:45:16.609: ISDN Se0/1/0:15 Q931: RX <- DISCONNECT pd = 8 callref = 0x8CDC
Cause i = 0x8090 - Normal call clearing
Progress Ind i = 0x8288 - In-band info or appropriate now available

015410: Mar 22 11:45:16.610: ISDN Se0/1/0:15 Q931: call_disc: PI received in disconnect; Postpone sending RELEASE for callid 0x8C5D

This is after a disconnect so not necessarily a call drop or failure issue.

That call lasted for about 322 seconds -

015409: Mar 22 11:45:16.610: %ISDN-6-DISCONNECT: Interface Serial0/1/0:0 disconnected from 8373996267 , call lasted 322 seconds

Now it is odd for your Telco to play a disconnect tone after an active call is being disconnected. This is usually seen when the external cell phone is switched off/DnD etc. So, your issue seems to be with the Telco.

Contact your ISP.
