Hi there,
old System:
Crystal-HW, CPU-6-Step-2, f1.603.1.aj (Rel.6.0.1) in ACT-14 at the Main Site. One additional WM-1 Shelf connected via INTOF-link.
After migration:
Common-HW, AS-IBM x3250M3, i1.605.25.b (Rel.9.1). At the Main Site there are three Shelfs with one GD-3, and one separated GD-3 with two Shelfs. One T2-Link for external communcation.
We´ve implemented an extra VLAN only for the OXE components (Alcatel Switches 6850). There are NO Ip-Phones, NO VoiceMail. Simple and straight config.
After the migration, we´ve experienced an issue regarding fax connections. The connection is established, but sometimes, the connection is refused without any reported cause...the error doesn´t occur in a reproducable way...sometimes, if we´re testing the connections, we´re causing fax connections with up to 20 pages without any issue...but sometimes, we cannot get one regular fax connection...we´ve already contacted ALU. All fax-machines are affected. We´ve tested with analog-Ports which are declared in the same shelf as the t2-link, with other ports declared in different shelfs as the t2-link, with analog-TA´s. The issue occured in all the conditions. Also, if we make internal fax connections (from one fax machine to another without t2) the issue also occurs randomly...
Also the analog RMA-Connection seems to be influenced...you can "hear" that the modem sounds seems to be produced in "slow motion"...
Incvisu and trace files are created, but there are no hints to solve the problem.
We´ve spoken with some other Alcatel-Partners and they told us, that ther might be a problem with patch 25.b?
Perhaps someone also experienced these kind of problems.
Thanks a lot for your support.
Best Regards
Michi
