I have an Asterisk server with 3 TDM400P cards. 9 FXO and 3 FXS ports.
It also has 2 Astribank-8 units connected. The customer is having calls
dropped at random intervals but several times a day. Could this be an issue
with Interrupts with the 3 cards?
I am also having a problem sending and receiving faxes when they are
either connected to the Astribank or to an FXS port on the TDM card. I know
there are issues with Asterisk and faxes but I have never had so many problems
in a single installation. Some faxes go through (mostly to local numbers) but
long distance calls always give a transmission error on the fax machine.
Any tips? I am using Asterisk 1.2.13 and Zaptel 1.2.11 on a CentOS 4.4
dual core server.

You should be able to see where this hangup came from.> > I am also having a problem sending and receiving faxes when they are > either connected to the Astribank or to an FXS port on the TDM card.

Do you guarantee that faxes go on a channel with no echo cancelling? If you want to fak from the ports of the Astribank, you'll probably need to use adj_clock . Also make sure that you set the kernel parameter prefmaster of xpp to 0, so it won't force itself t become the zaptel master.> > Any tips?

I've been getting a number of dropped calls today with the following visible in the logs: Feb 5 12:06:29 DEBUG[8340] channel.c: Bridge stops because we're zombie or need a soft hangup: c0=SIP/peachnet-213243-b7830fd8, c1=SIP/2142-08f4b6a0, flags: No,No,No,Yes Feb 5 12:06:29 DEBUG[8340] channel.c: Bridge stops bridging channels SIP/peachnet-213243-b7830fd8 and SIP/2142-08f4b6a0 Feb 5 12:06:29 DEBUG[8340] res_features.c: Timed out for feature!
