Matter: |
- one THS (Test Handset) can not be called - Alcatel sends busy status if it is called |
Summary | |
Description: |
After a while of operation of a THS HS Alcatel sends busy if a the HS gets called. Even an outgoing call from the THS is not possible. The Alcatel Extension where the THS is subscribed seems to be blocked. After unsubscribing and re-subscribing the extension works normal again. A test should clarify the reason and the unit which causes this behavior.
|
Test set up: |
- 1 CHS (CHS_1) subscribed at PABX as GAP (GAP+) - 1 CHS (CHS_2) subscribed at PABX as GAP+ (GAP) - 1 THS (THS_1) subscribed at PABX as GAP+ - 1 THS (THS_2) subscribed at PABX as GAP+ - 1 THS (THS_3) subscribed at PBAX as GAP - 1 THS (THS_4) subscribed at PBAX as GAP (CHS: Comparative Handset, THS: Test Handset) |
Test procedure: |
- take 2 HS (GAP/GAP or GAP/GAP+ or GAP+/ GAP+) - make a call between them - remove the battery of one HS (no power) during the call - insert the battery again - do new calls between the 2 HS |
Result: |
- blocking an extension can be reproduced be removing the battery of the GAP HS during an ongoing call - happens to extensions with GAP subscribed HS only - if GAP+ battery is removed, GAP+ HS rings after battery insert, after hook off, pending call can be continued, no blocking GAP HS - CHS HS and THS HS showthe samebehavior => Alcatel OmniPCX issue - effected blocked CHS show the same PABX- Message (“insufficient resources”) in display as DnA found in the DECT air trace during analyzing the issue at - self-unblocking ca. after 1min if GAP- GAP+ call was interrupted - no self-unblocking if GAP - GAP call was interrupted, until now, just rebooting PBAX is a known solution to free extension for GAP HSs, GAP+ is no problem |
Solution: | subscribe all HS as GAP+ at Alcatel OmniPCX |
