PAUSE STATUS CHANGES AFTER SET FROM AGENT API

Hi,
I can't figure out yet why this happens not always but frequently:
I get these response messages using the agent api with subsequent synchronous ajax calls from my webform app:
common.js:200:SUCCESS: external_pause function set - PAUSE|1387185948|6666
common.js:219:SUCCESS: external_hangup function set - 1|6666
common.js:236:SUCCESS: external_status function set - SALE|6666
seems to be ok so far and watching the agent screen shows it works well - though frequently only a second or less later
the status changes from pause to ready and I get the next call.
Any hints where to look for the reason for this behaviour?
Cordially,
Axel
