|Summary:||ASTERISK-05231: 1.2.0beta1 ISDN strong&weird noise|
|Date Opened:||2005-10-04 07:00:49||Date Closed:||2005-10-04 19:24:49|
|Description:||We just installed the 1.2b1 version to test it and have problems with modem channels.|
Until today we succesfully ran a 1.0.7-stable with one BRI ISDN Card (Asuscom, Hisax type 35) as a common office PBX, in Belgium, with tone dialing.
With the same hardware, the 1.2b1 has noise problem:
* ISDN party is ok, but the other party (SIP/IAX) receives loud noise;
* ISDN party can hear other party but with a long delay (about 1 sec)
* When only using asterisk applications such as Wait, Background, nothing was remarked, as we do not have another "external" channel
* We also tried with another Hisax card, type 11 (Eicon DIVA) but the problem remains.

alterys, please try chan_misdn (http://bugs.digium.com/view.php?id=4077) -- it is getting much more development.
