Hello everyone,
I finally have ISDN up and running on my soekris net4801 test system
here using the components mentioned above. Many thanks to Hans Petter
Selasky for getting support added for the card I'm using and
troubleshooting.
Here's how everything is connected.
ISDN Phone (2600) <--> ISDN pbx <--> ISDN TE Port (2601) on Asterisk System
Calling the conference (and other internal phones) from the ISDN phone
results in choppy audio from the music on hold as well as from other
conference members. ztdummy is loaded but seems to not be working
properly.
Even before attempting ISDN support, conferences were accumulating
delay. I have already enabled "internal_timing" and "highpriority" in
asterisk.conf to give it priority over other processes on the machine.
zttest gives me a worst score of 99.975586 after 10 passes. This gets
much worse if I attempt to do other things on the box while it runs.
Shouldn't it be accurate as long as the CPU isn't completely
overwhelmed? Any pointers here? Is there a way to pull timing from the
ISDN card?
Also, when calling extensions connected to the Asterisk system (SIP,
conferences, etc) from the ISDN phone (2600) sometimes they are
hung-up after a few hundred milliseconds. Calling back repeatedly
results in some calls being successfully connected and other silently
canceled. I have seen this issue before and resolved it by adding a
Wait(1) to give the ISDN systems time to sync and be happy. This has
not solved the issue this time. Has anyone seen something like this?
Let me know what additional output would be of use.
Thanks in advance for any insight into these problems!
-Michael I.
