One rather common problem (which started the most recent thread on the subject) is the card simply fails to process pstn-fxo calls. Most seem to suggest it happens about once per week or two. When it fails, reloading the drivers clears the problem (which requires taking * down to do it). There are no log messages to hint at why.
Another problem is documented in bug #2023 (and 2022), which describes voicemails left via a pstn-tdm call are consistently very low volume. ------------------------ > What exactly are people seeing when they have "issues" with their TDM > card? > > > Brian Greul > Texas Shirt Company > www.txshirts.com > 713-802-0369 / 713-861-6261 (fax) > > -----Original Message----- > From: Rich Adamson [mailto:[EMAIL PROTECTED] > Sent: Saturday, January 01, 2005 3:09 PM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: Re: [Asterisk-Users] Qs about FXO/FXS cards > > > I am going to be putting together my first * system using FXO/FXS > > interfaces.
