We have IPOffice 406v2 running v3.1.56, with ISDN30 (14 channels).
On occasions the default number for the ISDN30 bearer is sent as the calling number, and not the DDI number which the system is configured to send. Consequently we get incoming calls to the default number (and obviously the wrong extension/group) if called parties return missed or voicemail/answerphone calls.
We are running a log on the system which shows that the IP Office thinks it is sending the correct (DDI) number. Our IPO system maintainer is convinced it is an ISDN problem, and ISDN supplier (Unicom) is adamant it is a IPO system problem. It manifests itself as an infrequent and random problem - we have tried repeatedly to recreate the problem unsuccessfully. One guess I have so far is that it could be one of the channels on the ISDN30 always sending default number - consequently the problem seems intermittent.
If anyone has seen this or anything similar please post a reply/suggestions etc.
Thanks
