asterisk users - Sep 2004 - Crossed lines - a worrying problem.

Hi all,

I have just received the following e-mail from an Asterisk user:

"I just made a call via BT to a mobile. Then an incoming call came in and
Ann else answered it - it made my call go completely fuzzy and I could hear
what the woman on the other line was saying to Ann but I couldn't hear my
conversation!  When Ann's call finished - mine went even fuzzier and all I
could hear was computer and internet noises."

The setup is:

Asterisk box AMD Duron 1600, 256MB
Slackware 10
Asterisk RC1
One 'Fritz!' ISDN card (fcpci/chan_capi)
Four Grandstream BudgeTone 101 handsets
It's a shared 100bT LAN with three PCs and a printer, no strenuous file
copying etc. Network utilisation is very low. All the kit have 'real' IP
addresses.

Has anybody got any ideas what could possibly be causing this worrying
problem?

Cheers,

Nick Barnes

We also suffer from clicking and crosstalk with asterisk, chan_capi and
an Eicon Diva 4BRI when handling simultaneous calls. It seems to come
from SMP and/or kernel 2.6.x. No solution yet.

Yeah, I've had that happen too, even on a bog standard POTS call.

I'd blame the mobile network.
