We have a client with CCME 4.3, 7940 and 7911 phones, and ISDN PRI complaining about some calls being dropped prematurely (they claim only calls to a certain, third party provider, not the one giving them the ISDN line).<br>
<br>
However, debugging isdn q931 shows only Cause code 0x8090, "normal call clearing" for all the calls they've mentioned as prematurely disconnected.<br>
<br>
While I tend to believe it's a problem on their provider's side, it still disturbing, that the router is the one initiating the disconnect, not the provider. The calls can last anywhere from 0 to 20 seconds, but always disconnect normally.<br>
<br>
Any idea, what to debug now, to find out more?<br>
<br>
thanks,<br>
Zoltan<br>
