Hello,

I installed a Sangoma A108 with openzap and libpri. Signalling (E1)
works sometimes (inbound and outbound calls are connected) but not always.
Sound is just distortion but connection is stable.

2 questions:
1) What is the best way to go with Sangoma? OpenZAP with libpri or
without libpri? (I remember there are some timer problems in openzap
when not using libpri but this might have changed) However Sangoma
recommends OpenZAP on their wiki.
2) What might cause the distortion? I crosschecked the config files and
had a look at the interrupts (<2k/sec). Seems to be ok. ACPI and APIC is
turned on.

Freeswitch starts successfully with all the channels enabled. "oz dump"
shows D-Channel up.
"oz libpri debug 1 all" shows debugging messages with no special warnings.


Best regards
Peter
