[asterisk-users] outbound calls on PRI all congested

[Koopmann, Jan-Peter]

Hi,

 

I am just trying to but an Asterisk server between a German Telecom
(Deutsche Telekom) PMUX and a Siemens HiCom. Inbound Calls (Telekom ->
HiCom) work like charm. Outbound calls however all end up being
congested:

    -- B-channel 0/1 successfully restarted on span 1

 

 

Please excuse the number scrambling with "XXXX". I tried with dialplan
unknown and dialplan local. No change. We are using a Sangoma A104dx.
Any idea what could be causing the problem? If I reconnect the Hicom to
the Telekom PMUX everything is back to normal so the Telekom PMUX seems
to be operating normally.

 

Thanks a lot in advance!

 

Kind regards,

  JP
